acpi: Change Processor ACPI Name (Intel only)
The ACPI Spec 2.0 states, that Processor declarations should be made
within the ACPI namespace \_SB and not \_PR anymore. \_PR is deprecated
and is removed here for Intel CPUs only.
Tested on:
* X11SSH (Kabylake)
* CFL Platform
* Asus P8Z77-V LX2 and Windows 10
FWTS does not return FAIL anymore on ACPI tests
