soc/intel/apollolake and mainboards: Use pcie_rp_clkreq_pin array

This change uses an array pcie_rp_clkreq_pin for accepting CLKREQ#
from mainboards instead of defining a separate property for each root
port. This allows us to use memcpy to copy the entire array into FSP
params as well as new properties for PCIe root ports can be added as
arrays in future CLs.
