mtd: spinand: Sync core code and device support with Linux 6.17-rc1

Browse Source 
This makes the U-Boot SPI NAND driver almost the same as in Linux
6.17-rc1. The only major differences are:
 * support of ECC engines. The Linux driver supports different ECC
   engines while U-Boot uses on-die ECC only.
 * per operation maximum SPI bus frequency
