Subject: [PATCH AUTOSEL 6.12 299/486] drm/amd/pm: Fetch current power limit from PMFW

From: Lijo Lazar <lijo.lazar@....com>

[ Upstream commit b2a9e562dfa156bd53e62ce571f3f8f65d243f14 ]

On SMU v13.0.12, always query the firmware to get the current power
limit as it could be updated through other means also.
