mtd: rawnand: denali: set SPARE_AREA_SKIP_BYTES based on DT compatible
Currently, the denali NAND driver in U-Boot configures the
SPARE_AREA_SKIP_BYTES based on the CONFIG option.
Recently, Linux kernel merged a patch that associates the proper
value for this register with the DT compatible string.
Do likewise in U-Boot too.
The denali_spl.c still uses CONFIG_NAND_DENALI_SPARE_AREA_SKIP_BYTES.
