Subject: [PATCH AUTOSEL 4.14 033/103] soc: imx: gpc: fix PDN delay

From: Sven Schmitt <Sven.Schmitt@...ed-mode.de>

[ Upstream commit 9f4d61d531e0efc9c3283963ae5ef7e314579191 ]

imx6_pm_domain_power_off() reads iso and iso2sw from GPC_PGC_PUPSCR_OFFS
which stores the power up delays.
So use GPC_PGC_PDNSCR_OFFS for the correct delays.
