mtd: rawnand: ingenic: Fix ingenic_ecc dependency
If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m, which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails: drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove': ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release' drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct': ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct' To fix that, the ingenic_nand and ingenic_ecc modules have been fused into one single module. - The ingenic_ecc.c code is now compiled in only if $(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead of tristate. - To avoid changing the module name, the ingenic_nand.c file is moved to ingenic_nand_drv.c. Then the module name is still ingenic_nand. - Since ingenic_ecc.c is no more a module, the module-specific macros have been dropped, and the functions are no more exported for use by the ingenic_nand driver.
