acpi: Change Processor ACPI Name (Intel only)

Browse Source 
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

Sets the ACPI name string in the processor scope as written by
the acpigen function. Default is \_PR.CPxx. Note that you need
the acpigen function. Default is \_SB.CPxx. Note that you need
the \ escape character in the string.
