soc/intel/alderlake: Update maximum PCIe and TBT ports and clocks

ADL-S CPU has maximum 3 PCIe interfaces when the x16 link is bifurcated
into two x8 links. ADL-S PCH has up to 28 PCIe Root Ports, 18 CLKOUT and
CLKREQ signals. ADL-S CPUs do not have Thunderbolt.

Based on the Intel DOC #619501 and #619362.
