soc/intel/xeon_sp: Add get_cxl_mode
Configuration variable implementation (VPD, et al) is regarded to
be mainboard specific and should not be bounded to SoC codes.
Add get_cxl_mode so that SoC codes do not need to get this
configuration from VPD any more.
TEST=Build and boot on intel/archercity CRB with no significant log
differences
