Add api for SD host controller driver. SD host controller driver
supports the following operations:
- reset: reset host controller state
- request: send SD command and data via SDHC
- set_io: set I/O settings (voltage, clocks, etc..) on SDHC
- get_card_present: check for card presence
- execute_tuning: run tuning process for UHS cards
- card_busy: check if SD card bus is busy
- get_host_props: get host controller properties

LiteX CSRs can only be accessed on addresses aligned to 4 bytes.

Changes signature so it takes uint32_t instead of pointer to a
register.
Later `sys_read*` and `sys_write*` functions are used, which cast
given address to volatile pointer anyway.
This required changing types of some fields in LiteX GPIO driver and
removal of two casts in clock control driver.
There was a weird assert from LiteX GPIO driver, which checked whether
size of first register in dts was a multiple of 4.
It didn't make much sense, so I removed it.
Previous dts was describing size of a register in terms of subregisters
used. New one uses size of register, so right now it is almost always
4 bytes.
Most drivers don't read register size from dts anyway, so only changes
had to be made in GPIO and clock control drivers.
Both use `litex_read` and `litex_write` to operate on `n`bytes.
Now GPIO driver calculates this `n` value in compile time from given
number of pins and stores it in `reg_size` field of config struct like
before.
Registe sizes in clock control driver are hardcoded, because they are
tied to LiteX wrapper anyway.
This makes it possible to have code, independent of CSR data width.

Adds LITEX_CSR_DATA_WIDTH option to Kconfig
Depending on its value appropriate read/write handling is used
for accessing CSR registers.
By using `>=` in preprocessor conditions it is somewhat future-proofed.

Currently the driver only setup the ADC to read from the
internal temperature channel on init. However, it is possible
that some other application that uses the ADC can setup the
ADC to read from some other channel and therefore subsequent
stm32_temp_sample_fetch will fail to read the targeted channel.

The peripheral is configured to update the connection
parameters for 5 seconds by default.
There is an abnormal situation with a very low probability.
The central actively disconnects or abnormally disconnects the
Bluetooth connection at the same time.
At this time, the connection disconnection event will be
handled by BT RX.
At this time, sysworkq has sent a parameter update request and
will receive a reply with status = 0x02, because the handle is
invalid at this time.
We can not just cancel work, because work->flag may be
in K_WORK_RUNNING, so work->flag is set to K_WORK_CANCELING
and subsequent conn_cleanup will unable call k_work_rescheduler
successfully.
According submit_to_queue_locked will return ret = -EBUSY.
if (flag_test(&work->flags, K_WORK_CANCELING_BIT)) {
/* Disallowed */
ret = -EBUSY;
As a result, the connection cannot be cleanup correctly.

The NAPOT mode isn't computed properly in qemu when the full address
range is covered. Let's hardcode the value that the qemu code checks
explicitly until the appropriate fix is applied to qemu itself.

QEMU does its dynamic instruction translation in 4096-byte-sized chunks.
Therefore it doesn't vet PMP access for each instruction prefetch but
for the whole "page" at once. If the end of the ROM area lands in the
middle of such a page with a corresponding PMP entry then any instruction
access within that page will fault even if it is located in the PMP
mapped portion.
To work around this QEMU peculiarity, we simply align the end of the ROM
area to a page boundary.

Stackguard uses the PMP to prevents many types of stack overflow by
making any access to the bottom stack area raise a CPU exception. Each
thread has its set of precomputed PMP entries and those are written to
PMP registers at context switch time.
This is the code to set it up. It will be connected later.
