mtd: rawnand: gpmi: Restore nfc timing setup after suspend/resume
commit5.4-rM2-2.2.x-imx-squashedd70486668c
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. Fixes:ef347c0cfd
