soc/intel/tigerlake: Add soc_get_cpu_rp_vw_idx() function

The PMC IPC method used to enable/disable PCIe clk sources uses the
LCAP PN field to distinguish PCH RPs. For CPU RPs, the PMC IPC
command expects the RP number to be its "virtual wire index"
instead. This new function returns this virtual wire index
for each of the CPU PCIe RPs.
