Subject: [PATCH -next] mtd: rawnand: stm32_fmc2: Make some functions static

Fixes the following sparse warning:
drivers/mtd/nand/raw/stm32_fmc2_nand.c:1228:6: warning: symbol 'stm32_fmc2_read_data' was not declared. Should it be static?
drivers/mtd/nand/raw/stm32_fmc2_nand.c:1275:6: warning: symbol 'stm32_fmc2_write_data' was not declared. Should it be static?
drivers/mtd/nand/raw/stm32_fmc2_nand.c:1707:32: warning: symbol 'stm32_fmc2_nand_ooblayout_ops' was not declared. Should it be static?
