[PATCH 8/8] drivers: mtd: nand: HSD #1508104447-13: mtd: nand: raw: denali: Wait for reset completion status

From: Ley Foon Tan <ley.foon.tan at intel.com>

Fixed delay 200us is not working in certain platform. Change to
poll for reset completion status to have more reliable reset process.

Controller will set the rst_comp bit in intr_status register after
controller has completed its reset and initialization process.
