mtd: mxc_nand: dont call suspend and resume explicitly
The mtd layer is responsible to call mtd->{suspend,resume}. Doing it
again in the driver is wrong and results in a warning:
nand_resume called for a chip which is not in suspended state
at resume time. Removing the calls from the resume and suspend
functions makes them empty allowing them to be deleted completely.
