soc/intel/alderlake: Skip PCIe source clock assignment if incorrect
When an enabled root port without pcie_rp clock being specified, the empty structure provides invalid info, which indicates '0' is the clock source and request. If a root port does not use clock source, it should still need to provide pcie_rp clock structure with flags set to PCIE_RP_CLK_SRC_UNUSED. If flags, clk_src, and clk_req are all '0', it is considered that pcie_rp clock structure is not provided for that root port. Add check and skip for enabled root port that does not have clock structure. In addition, a root port can not use a free running clock or clock set to LAN. Note that ClockUsage is either free running clock, LAN clock, or the root port number which consumes the clock.
