mtd: denali: remove unnecessary stubs
This driver uses NAND_ECC_HW_SYNDROME mode. The nand_scan_tail() function would not complain about missing ecc->calculate, ecc->correct, ecc->hwctl handlers. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
