soc/amd: Refactor DPTC Tablet Mode
Refactor AMD DPTC tablet mode in preparation for adding low/no battery
DPTC settings.
1. Refactor and simplify acpigen_write_alib_dptc() into the following
functions:
- acpigen_write_alib_dptc_default()
- acpigen_write_alib_dptc_tablet()
2. Add device tree register value dptc_tablet_mode_enable to control
whether DPTC tablet mode is enabled for a variant.
3. Add dptc.asl to perform the necessary ACPI checking before modifying
the DPTC settings.
