[PATCH 3/6] mtd: nand: mxc: Remove useless checks in GET/SET_FEATURES functions

[Miquel Raynal]

From: Miquel Raynal <miquel.raynal at free-electrons.com>

All the calls to the chip's hooks ->onfi_get/set_features() go through
the core's wrappers nand_get/set_features() that already do the
necessary checks about ONFI compliance and feature support. Remove these
checks from the mxc's functions.
