acpi: Replace EC_ENABLE_AMD_DPTC_SUPPORT with Kconfig value

Compile-time support of DPTC is controlled by
EC_ENABLE_AMD_DPTC_SUPPORT in each variant's ec.h file. This CL removes
EC_ENABLE_AMD_DPTC_SUPPORT and replaces it with the Kconfig value
SOC_AMD_COMMON_BLOCK_ACPI_DPTC.

Each variant's run-time support of DPTC continues to be controlled by
the variant's overridetree.cb "dptc_enable" value.
