skylake: dptf: Add TSR3 thermal sensor and CPU code cleanup
- glados has more thermal sensors that could be used so add
another entry in the DTPF thermal sensor ACPI code.
- fix indentation block in cpu.asl.
- declare \_SB.MPDL as external (it is already CondRefOf)
so it does not need to be present in mainboard config if
the mainboard does not want to override the default.
BUG=chrome-os-partner:44622
BRANCH=none
TEST=emerge-glados coreboot
