Victor Rajewski 730525cec9 stm32/qspi: Allow qspi_write_cmd_data to write cmd with 1 data byte.
The existing qspi for stm32 implementation can only send a spi command with
exactly 0 or 2 data bytes.  Certain spiflash chips (e.g. AT25SF321B) have
commands that only take a single data byte, and will ignore the command if
more than that is sent.  This commit allows sending a command with a single
data byte.
