soc/intel/common/acpi,mb/*: replace the two obsolete LPID with PEPD
Replace the two obsolete LPID implementations with the new PEPD device.
The PEPD device gets included in the plaforms' `southbridge.asl`, since
it is required to load the `intel_pmc_core` module in Linux, which
checks for the _HID. (See CB:46469 for more info on that.)
There is no harm for mainboards not supporting S0ix, because the _DSM
function won't be called with the LPS0 UUID on such boards. Such boards
can use the debugging functionality of `intel_pmc_core`, too.
