amd/cezanne: Control DPTC with only Kconfig 

SOC_AMD_COMMON_BLOCK_ACPI_DPTC can be enabled conditionally for any
guybrush boards, similar to .mainboard/google/zork/Kconfig This makes
the value dptc_tablet_mode_enable redundant.

This CL removes dptc_tablet_mode_enable so DPTC is controlled entirely
with the Kconfig value SOC_AMD_COMMON_BLOCK_ACPI_DPTC. This means DPTC
is only included for boards that actually enable it.
