ARM: at91: Convert SPL_GENERATE_ATMEL_PMECC_HEADER to Kconfig

This commit converts the following items to Kconfig:

CONFIG_ATMEL_NAND_HWECC
CONFIG_ATMEL_NAND_HW_PMECC
CONFIG_PMECC_CAP
CONFIG_PMECC_SECTOR_SIZE
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER

Fixes: 5541543f ("configs: at91: Remove CONFIG_SYS_EXTRA_OPTIONS assignment")
[trini: Make the migration be size neutral and possibly not fix the
above in all cases]
