mtd: nand: sunxi: Fix not calling dev_err with a device

Usually the device is gotten from sunxi_nfc. This is a struct device and
not a struct udevice, but the whole driver seems to be written wihout DM
anyway...

In a few instances, this patch modifies functions to take an nfc to log
with. In once instance we use mtd_info's device since there is no nfc.
