Add an optional DT property to specify the size of the RX/TX FIFO
implemented within the SPI core. The property name used is the same one
used by Xilinx's device tree generator.
When the FIFO is known to exist, we can use the RX FIFO occupancy register
to determine how many words can be read from the RX FIFO without checking
the RX FIFO empty flag after every read. Likewise with the TX FIFO, we can
use the FIFO size to avoid checking the FIFO full flag after every write.
This can increase overall throughput.

Add support for a workaround required when using the Xilinx Quad SPI core
with the USE_STARTUP option, which routes the core's SPI clock to the
FPGA's dedicated CCLK pin rather than a normal I/O pin. This is typically
used when interfacing with the same SPI flash device used for FPGA
configuration. In this mode, the SPI core cannot actually take control
of the CCLK pin until a few clock cycles are issued, which would break
the first transfer issued by the core. This workaround applies a dummy
command to the connected device to ensure that the clock signal is in the
correct state for subsequent commands.

These three sensor types are all largely compatible. The SHT21 and
HTU21D can be supported by this driver by sending command 0xE3 instead
of 0xE0 to read the temperature.
Mention the sensor names in bindings and Kconfig to help those looking
for support to find it. There have been at least five PRs attempting to
add SHT21 and/or HTU21D support that did not realize the Si7006 is the
same.
As mentioned in PR #22862, the Sensirion SH21 is the original. The dts
bindings are adjusted (in a backward compatible way!) to make the sht21
the base binding and si7006 is derived from that.
Examples of dts compatibles:
TE Connectivity née Measurement Sepcialties HTU21D:
compatible = "meas,htu21d", "sensirion,sht21";
Sensirion SHT21:
compatible = "sensirion,sht21";
Silicon Labs Si7006
compatible = "silabs,si7006";
Silicon Labs Si7021
compatible = "silabs,si7021", "silabs,si7006";

Add a mailbox driver for VEVIF events (VPR irq).
The driver can be built in either 'rx' or 'tx' configuration.
The VPR sends the event, so it uses the 'tx' configuration,
while the master core uses the 'rx' configuration of the driver
to receive the VPR events.

Add CMSIS-DAP compatible controller which is a handler between
the host interface and SWD driver. The controller follows CMSIS-DAP
reference implementation. It expects a request buffer from the host
interface, splits it to simple transfers and forwards to the DP driver,
and finally returns a response buffer to the host.
Interface to the host can be implemented with USB HID device support.
Controller implements only SW-DP support and is tested
with pyOCD and ADIv5.x.

Add Serial Wire Debug Port interface driver API and bit-bang driver.
The driver requires a simple Hardware Interface Circuits (HICs),
where signals CLK, DOUT, DIN, ENn, OE_ENn, RESETn
are connected to board GPIOs and buffered signals SWD_CLK and SWD_DIO
to the target.
Signal OE_ENn controls the direction of the Serial Wire (SWD_DIO),
ENn the buffers SWD_CLK possibly others and enables/disables HIC.

LPC GPIO binding was wrong in that the reg address
on the simple soc bus was given as an index of the gpio ports
within a gpio controller. Fix this by putting the GPIO node
on the simple bus as a single node with the correct base address,
and make the ports children of this node.
Change the driver to get the port number from the reg address
instead of a custom property, and get base address from DT instead
of the SDK macro definition.
