zephyr: add DPTF support
Add a Kconfig option to enable DPTF support. Adds support for the
following ACPI entries:
EC_ACPI_MEM_FAN_DUTY (0x04)
EC_ACPI_MEM_TEMP_ID (0x05)
EC_ACPI_MEM_TEMP_THRESHOLD (0x06)
EC_ACPI_MEM_TEMP_COMMIT (0x07)
BUG=b:179886912
BRANCH=none
TEST=zmake testall
TEST=Boot zephyr-ec on Volteer, observe that ACPI warnings for ignored
read/writes for DPTF commands are fixed.
