platform/x86/amd/pmf: Fix to update SPS thermals when power supply change

[ Upstream commit de2601a9f3d38fbe95a12dccaad2b78ccbad65eb ]

Every power mode of static power slider has its own AC and DC power
settings.

When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.

Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.
