x86/intel: insert Ice Lake-SP and Ice Lake-D model numbers

LBR, C-state MSRs should correspond to Ice Lake desktop according to
SDM rev. 74 for both models.

Ice Lake-SP is known to expose IF_PSCHANGE_MC_NO in IA32_ARCH_CAPABILITIES MSR
(as advisory tells and Whitley SDP confirms) which means the erratum is fixed
in hardware for that model and therefore it shouldn't be present in
has_if_pschange_mc list. Provisionally assume the same to be the case
for Ice Lake-D.
