Convert CONFIG_NAND_OMAP_ECCSCHEME to KconfigWIP/2021-10-06-assorted-improvements

The values of CONFIG_NAND_OMAP_ECCSCHEME map to the enum in
include/linux/mtd/omap_gpmc.h for valid ECC schemes.  Make which one we
will use be a choice statement, enumerating the ones which we have
implemented.

-	- hardware engines present in SoC.
-		Some legacy OMAP SoC do not have ELM h/w engine thus such

-	- size of OOB/Spare region
-		With higher ECC schemes, more OOB/Spare area is required to
-		store ECC. So choice of ECC scheme is limited by NAND oobsize.
-
-	In general following expression can help:
-		NAND_OOBSIZE >= 2 + (NAND_PAGESIZE / 512) * ECC_BYTES
-	where
-		NAND_OOBSIZE	= number of bytes available in

-		NAND_PAGESIZE	= bytes in main-area of NAND page.
-		ECC_BYTES	= number of ECC bytes generated to
-				protect 512 bytes of data, which is:
-				3 for HAM1_xx ecc schemes
-				7 for BCH4_xx ecc schemes
-				14 for BCH8_xx ecc schemes
-				26 for BCH16_xx ecc schemes

-		example to check for BCH16 on 2K page NAND
-		NAND_PAGESIZE = 2048
-		NAND_OOBSIZE = 64
-		2 + (2048 / 512) * 26 = 106 > NAND_OOBSIZE
-		Thus BCH16 cannot be supported on 2K page NAND.
