fel: SPI: add Macronix support

Add the JEDEC manufacturer ID for Macronix to the list of recognized
vendors, also add the MX25L series to the list of supported chips.
Those chips are used on the OrangePi PC 2 boards, for instance.
Tag the struct definition with the member names on the way to improve
readability of the SPI flash chip description.
