mtd/spinand: sync supported devices with linux-5.15.43

Browse source 
This adds more supported spinand devices from the Linux kernel
implementation.

This does not include the latest kernel implementation as this would
require a substantial amount of extra work due to the missing
ECC engine abstraction layer in U-Boot.
