Subject: [PATCH] drm/amd/pm/powerplay/hwmgr/smu_helper: fix order of mask and value

There is a small typo in phm_wait_on_indirect_register().

Swap mask and value arguments provided to phm_wait_on_register() so that
they satisfy the function signature and actual usage scheme.

Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
