drivers: flash: flash_mcux_flexspi_nor: check all 3 bytes of JEDEC ID

The FlexSPI NOR driver should verify all 3 bytes of the JEDEC ID match
the expected value before attempting to use a custom LUT table with a
flash chip. This reduces the odds that an incompatible LUT will be used
with a flash chip, as some flash chips may share the same first byte of
their device ID but not be compatible with the custom LUT table.
