From: Boris Brezillon <boris.brezillon@bootlin.com>

[ Upstream commit 732774437ae01d9882e60314e303898e63c7f038 ]

The opcodes used by the controller when doing batched page prog should
be written in NFC_REG_WCMD_SET not FC_REG_RCMD_SET. Luckily, the
default NFC_REG_WCMD_SET value matches the one we set in the driver
which explains why we didn't notice the problem.
