drm/amd/pm: fix smu13 power limit default/cap calculation
smu_v13_0_0_get_power_limit() and smu_v13_0_7_get_power_limit() mix
runtime power_limit with PP table limits when reporting default/min/max.
When current power limit query succeeds, default_power_limit was set to the
runtime value instead of the PP table default, and min/max could be derived
from inconsistent bases (MsgLimits/runtime), leading to incorrect cap info.
Use SocketPowerLimitAc/Dc as the PP default base (pp_limit), keep
current_power_limit as runtime value, and derive min/max from pp_limit with
OD percentages.
