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 Tested-by: Angel Pons <th3fanbus@gmail.com> Change-Id: Ib101ed718f90f9056d2ecbc31b13b749ed1fc438 Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/37814 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>
