Subject: [PATCH] sb/intel/wildcatpoint/acpi: Move platform.asl to mainboards

The chipset platform.asl only provided empty _PTS/_WAK stubs and _SWS
methods, which mainboards needing custom sleep/wake behavior (e.g. EC
methods) cannot use. Only 2 of 5 Wildcat Point boards used it. Move the
content to mainboard code and inline the device_nvs and common platform
includes in dsdt.asl to align with other Wildcat Point and Lynx Point
boards. Keeping device NVS in mainboard code also simplifies future
Lynx/Wildcat unification.

Tested with BUILD_TIMELESS=1, Purism Librem 15 v2 remains identical.
