This partly reverts commit 28c015a9daabe4ed3aeb0ccf669a3f1c2b8b81d5.

Since f6d7c1b5598b ("mtd: nand: davinci: Reinitialize the HW ECC
engine in 4bit hwctl") using subpage and 4bit HWECC works.

Revert the original workaround made for this. Tested with
mtd_subpagetest and UBIFS on K2E, K2HK, K2L EVMs.

The addition of keystone specific compatible to davinci_nand_of_match[]
contained in original commit is retained.
