soc/intel/xeon_sp/spr: Drop devicetree setting X2apic

Drop devicetree setting X2apic as the same functionality is already
exposed in Kconfig.

To activate X2apic select X2APIC_ONLY or X2APIC_RUNTIME in
the "APIC operation mode".

Note: Your OS must have support for X2APIC. If you are using less
      than 256 CPU cores select XAPIC_ONLY here.

Test:
- Booted to OS in X2APIC mode when X2APIC_ONLY or X2APIC_RUNTIME
  was selected.
- Booted to OS in XAPIC mode when XAPIC_ONLY was selected.
