[ 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.
