The first transfer in an I2C transaction series must always set
the RESTART flag. Since this is not always done by callers,
enforce the flag is set, both in the I2C API and RTIO API entry
points of STM32 I2C RTIO drivers.
Add a sanity test in STM32 I2C v2 RTIO driver on transaction
chunks regarding RESTART and STOP flags, as done on the non-RTIO
driver.

This change modifies the secure proxy mailbox driver to pass user data
to the interrupt service routine (ISR) callback. This allows the ISR
to access the specific context or data associated with the mailbox
message being processed.

CLOCK_CONTROL is required for fast instances of UART and COUNTER,
help select it when possible. The fast instances are UARTE120,
TIMER120 and TIMER121, and CLOCK_CONTROL is not supported for
CPUFLPR and CPUPPR even when the fast instances are used.

Support for 8 dummy cycles in a single line RX transaction is required
for the standard JEDEC Read SFDP command. The SSI controller does not
support dummy cycles in Standard SPI mode, but the driver can simulate
those by just sending a dummy data byte.

Immediately finish an RX transfer when the RX FIFO overflow is
encountered and return the -EIO error code, which better indicates
the problem than -ETIMEDOUT that was returned previously in such
case.

- use separate code paths for TX and RX in ISR
- make sending of dummy bytes in the single line mode (Standard
SPI) more consistent so it can be easily extended
- use value 0 instead of 0xAA for dummy bytes as there is normally
no point in making noise one the MOSI line when only receiving
data (it can only be useful in debugging transfers)
- move all writing of data in the TX FIFO to ISR to avoid broken
transfers in the single line mode (where the clock stretching
is not available) when the driver is preempted right before it
enables interrupts
- use the TX FIFO start level also for transfers without data,
so that it's not possible that the TX FIFO gets emptied between
the writes of command and address fields in the single line mode
- add a few comments to explain better how transfers are handled

After the START task is triggered, the clock that drives the SSI core
needs some time to become ready. Before that, writes to SSI registers
may be unsuccessful. Add a loop that performs test writes to one of
the registers after the EXMIF peripheral is resumed to ensure that it
is fully operable.

- add checks for maximum supported address length
- correct *_WAIT_CYCLES_MAX macros used in XIP handling routines
