x86/split_lock: Enumerate architectural split lock disable bit
The December 2022 edition of the Intel Instruction Set Extensions manual
defined that the split lock disable bit in the IA32_CORE_CAPABILITIES MSR
is (and retrospectively always has been) architectural.
Remove all the model specific checks except for Ice Lake variants which are
still needed because these CPU models do not enumerate presence of the
IA32_CORE_CAPABILITIES MSR.
