[PATCH AUTOSEL 4.19 098/177] pinctrl: amd: fix __iomem annotation in amd_gpio_irq_handler()

[Sasha Levin <sashal@xxxxxxxxxx>]

From: "Ben Dooks (Codethink)" <ben.dooks@xxxxxxxxxxxxxxx>

[ Upstream commit 10ff58aa3c2e2a093b6ad615a7e3d8bb0dc613e5 ]

The regs pointer in amd_gpio_irq_handler() should have __iomem
on it, so add that to fix the following sparse warnings:
