By default, a dedicated INT GPIO is prioritized, even if the sensor
is on an I3C bus.

I3C is now a bus supported, by relying on RTIO IODEV which is supported
for all buses (I2C, I3C and SPI). Tested backwards compatibility: I2C
and I3C.

Use cache API for disabling and enabling ICACHE. The driver handles waiting
for ongoing cache invalidation.
Signed-off-by: Henrik Lindblom <henrik.lindblom@vaisala.com>
STM32 Cortex-M33, such as the L5/H5/U5 series, have a cache peripheral for
instruction and data caches, which are not present in the C-M33
architecture spec.
The driver defaults to direct mapped cache as it uses less power than the
alternative set associative mapping [1]. This has also been the default in
stm32 soc initialization code for chips that have the ICACHE peripheral,
which makes it the safest choice for backward compatibility. The exception
to the rule is STM32L5, which has the n-way cache mode selected in SOC
code.

There are warnings generated within NVMe. `prp` is a `void *` which
is 32bits wide on 32bit systems. This adds a cast to first cast it
to a `uintptr_t` and then casts it to a `uint64_t` to supress the
warning.
This also fix an issue where `int n_prp` is defined under a case
statement. This adds the { } around the block underneath it.

Support SPI_HOLD_ON_CS flag in the CPU-based driver. To do this we will
set CONTC bit to continue previous command. Technically it may not be
necessary right now, and could just not clear CONT bit...
but in the future in the lpspi driver we
will decouple the config/init of a transfer from the SDK
and therefore have more control over TCR,
and when we write the TCR, we need to take CONTC bit into account
otherwise a new command will be made. So this approach is how
it should be handled in the driver going forward in my opinion, even
if it might be possible without this bit right now, I want to introduce
it's usage now.
This commit also does a minor refactor in the ISR and adds some comments
to make the strange CS behavior and strange handling code more clear to
future readers.
Also, make the early predicted SPI xfer end code only happen for spi
versions where it is necessary, since I think that code is really the
best we can do but might have a race condition, where possible the last
word is not finished sending when we end the xfer. So limit the
potential affect to v1 lpspi where the workaround is actually required
due to stalling behavior.
Lastly, set the LPSPI into master mode at active low in init, due to
it being the most common case, we want the SPI CS lines to be
initialized at init of driver. I don't think it's worth it to make it
configurable at this time, but in the future it could be if needed.

Optimize the TX fill algorithm to have less interrupts by filling the TX
fifo as much as possible during each interrupt handle.
Before, the algorithm was just a very simple, fill the TX fifo with as
much from only the current buffer as possible, then send it and wait for
the next interrupt. Now the algorithm is to fill the TX fifo as much as
possible, even if it means reading from multiple buffers during the
interrupt.
This has the advantage from master mode of having less interrupts. And
it is very important for slave mode because the slave mode does not
control the pacing of the transfer and so therefore should fill as much
as possible whenever possible in order not to miss a deadline.

The new DSA framework purpose and changes are as below.
- Aligned to Linux DSA framework which has been already mature framework
for many years, For now in zephyr, the DSA components were splited
as: switch, port, master(not need driver file for now), slave, and tag.
Seperated drivers were used for maintaining and developing new
features.
- The unified dts bindings (aligned to linux) were supported. The port
driver would parse DTS to decide the port type (master port, slave
port, or cpu port) to set up the switch. All the ports registered as
standard ethernet devices. (dsa port and dsa switch tree was not
supported.)
- How to add DSA device driver based on the framework? All the device
driver needing to do is providing dsa_spi implementation and private
data, and calling below initialization.
DSA_INIT_INSTANCE(n, _dapi, data)
- For switch tag case, recv/xmit helpers in dsa_api could be used for
taging/untagging. No modified ethernet drivers.
For no-tag type case, ethernet driver of master port should support
packet injection/extraction for slave ports leaving NULL recv/xmit.
The dsa_nxp_imx_netc.c driver will be the first example of the new DSA
framework.
The future work for DSA will be supporting bridge for ports. We may align
Linux to give users two options to use DSA device:
- Standalone mode: the switch ports work as regular ethernet ports.
- Bridge mode: switch mode with virtual bridge device which could be
assigned IP address.

Current DSA TX/RX way was hard-coded in ethernet devices driver
with ETH_DSA_SUPPORT and NET_DSA.
This patch is to make such way obsolete, as we actually will support
a better DSA framework to handle this in NET/DSA core driver.
To make legacy devices not affected, below options are used instead.
- ETH_DSA_SUPPORT_DEPRECATED
- NET_DSA_DEPRECATED
Once the legacy devices are converted to new DSA framework, this code
could be removed.

When GPIO17 or 16 is used as an external REF_CLK signal, the output is
enabled in eth_esp32.c This was added in PR number #65759 and then refined
in PR #74442. However this does not work for PHYs which need the REF_CLK
for MDIO communication, such as LAN8720A. In such cases phy_mii driver
tries to get the ID of such a PHY before REF_CLK is present. Therefore
in this PR I propose to move REF_CLK initialization from eth_esp32.c to
mdio_esp32.c which gets initialized before PHY and ETH.
