soc/amd/picasso: add dptc support
add dptc support for different power parameter on tablet/clamshell mode
The BIOS may choose to adjust power and/or thermal parameters at its own
discretion. The DPTC interface(DPTCi) ALIB Function adds flexibility by
allowing the BIOS to request power state changes independently of specific
events.
