soc/intel/skylake: Set xtal bypass on low power idle
When using Wake On Voice &/or DCI, it requires xtal to be active during
low power idle.
With xtal being active in S0ix state power impact is 1-2 mW.
Hence set xtal bypass bit in CIR31C for low power idle entry.
TEST= Build with s0ix enable for Poppy. Boot to OS & verify that
bit 22 of CIR31C register is set. s0ix works.
