6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@xxxxxx>
commit 6ad6e15a9c46b8f0932cd99724f26f3db4db1cdf upstream.
Firmware returns the physical address of the power switch,
so need to use gsc_writel() instead of direct memory access.
Fixes: d0c219472980 ("parisc/power: Add power soft-off when running on qemu")
