[PATCH v2 10/19] mtd: nand_mrvl_nfc: Fix num-cs property parsing

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

The "num-cs" property does not encode flashes CS line but number
of available CS signals. Fix wrong property parsing to ->cs by
adding proper ->num_cs variable to host struct.
