Subject: ACPI: EC: Fix debugfs_create_*() usage

From: Geert Uytterhoeven <geert+renesas@glider.be>


[ Upstream commit 3522f867c13b63cf62acdf1b8ca5664c549a716a ]

acpi_ec.gpe is "unsigned long", hence treating it as "u32" would expose
the wrong half on big-endian 64-bit systems.  Fix this by changing its
type to "u32" and removing the cast, as all other code already uses u32
or sometimes even only u8.
