[PATCH] platform/x86/intel/tpmi/plr: Make the file domain<n>/status writeable

[Ricardo Neri]

The file sys/kernel/debug/tpmi-<n>/plr/domain<n>/status has store and show
callbacks. Make it writeable.

I tested this patch in Sierra Forest and Granite Rapids-D systems.

$ echo 0 > /sys/kernel/debug/tpmi-<n>/plr/domain<m>/status
$ cat /sys/kernel/debug/tpmi-<n>/plr/domain<m>/status
cpus none
cpu0 none
cpu1 none

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
