mtd: rawnand: gpmi: Restore nfc timing setup after suspend/resume
commit d70486668cdf51b14a50425ab45fc18677a167b2 upstream.
As we reset the GPMI block at resume, the timing parameters setup by a
previous exec_op is lost. Rewriting GPMI timing registers on first exec_op
after resume fixes the problem.
