soc/intel/skylake: Add PcieRpClkSrcNumber UPD configuartion support
New UPD PcieRpClkSrcNumber introduced in FSP V2.9.2 to configure
clock source number of PCIe root ports. This UPD array is set to clock
source number(0-6) for all the enabled PCIe root ports, invalid(0x1F)
is set for disabled PCIe root ports.
BUG=b:70252901
BRANCH=None
TEST= Perform the following
1. Build and boot soraka
2. Verify PCIe devices list using lspci command
3. Perform Basic Assurance Test(BAT) on soraka
