spi: stm32-ospi: 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.
Running mtd_speedtest on a 4MB sNOR partition using a
stm32mp257f-ev1 board gives the following results:
before after gain
Read : 5693 KiB/s 21139 KiB/s 371%
Write: 765 KiB/s 910 KiB/s 19%
