The MediaTek Hardware ECC Engine is only present on MediaTek MT27xx and
MT76xx SoCs. The driver for this engine is a dependency for the
MediaTek NAND controller (MTD_NAND_MTK) and the MediaTek SPI NAND Flash
Interface (SPI_MTK_SNFI) drivers, both of which already depend on
ARCH_MEDIATEK.
Hence add a dependency on ARCH_MEDIATEK to the Hardware ECC Engine
driver, too, to prevent asking the user about this driver when
configuring a kernel without MediaTek SoC support.

This enables support for the hardware ECC engine from Mediatek.

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git nand/next, thanks.
