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.

- replace %d with %u in two error log message format strings
- add checks for maximum supported address length
- correct *_WAIT_CYCLES_MAX macros used in XIP handling routines
(although their values are valid, they belong to different SSI
registers)

- remove doubled definitions of the XIP_CTRL register bit fields
