spi: stm32-qspi: Optimize FIFO accesses using u16 or u32
FIFO accesses uses u8 only for read/write.
In order to optimize throughput, add u16 or u32 read/write
accesses when possible.
Set FIFO threshold level value accordingly.
Test performed by writing and reading 64MB on sNOR on
stm32mp157c-ev1 board:
before after ratio
Write : 428 KB/s 719 KB/s +68%
Read : 520 KB/s 3200 KB/s +615%
