drm/amd/pm: fix smu13 power limit range calculation
SMU13 reports SocketPowerLimitAc/Dc as the default power limit, but
MsgLimits.Power may carry a different firmware bound for the same PPT
throttler. Using only the socket limit for both min and max can therefore
expose an incorrect power range.
Keep the socket limit as the default, but derive the range from both values:
use the lower value for the min base and the higher value for the max base
before applying OD percentages. Keep the current limit query independent
from the cap calculation.
Fixes: 1eaf26db9590 ("drm/amd/pm: fix smu13 power limit default/cap calculation")
Closes: https://gitlab.freedesktop.org/drm/amd/-/work_items/5419
