A few functions provide an empty interface definition when
CONFIG_MTD_NAND_INGENIC_ECC is disabled, but they are accidentally
defined as global functions in the header:
drivers/mtd/nand/raw/ingenic/ingenic_ecc.h:39:5: error: no previous prototype for 'ingenic_ecc_calculate'
drivers/mtd/nand/raw/ingenic/ingenic_ecc.h:46:5: error: no previous prototype for 'ingenic_ecc_correct'
drivers/mtd/nand/raw/ingenic/ingenic_ecc.h:53:6: error: no previous prototype for 'ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_ecc.h:57:21: error: no previous prototype for 'of_ingenic_ecc_get'
Turn them into 'static inline' definitions instead.
