Merge patch series "airoha: add support spi/mmc/ethernet"

This is continuation of the initial patchset for airoha
support.

Some are trivial fix for spi.
A new concept to setup SPI from detected NAND.

Sadly DTS node still need to be merged upstream so we
are currently adding them to u-boot dtsi and it's planned
to be dropped once they are accepted in upstream kernel.
