soc/intel/skylake: Remove pch_enable_dev() from SoC

PCI resources MMIO space/bus master enabling is handled inside
pch_dev_enable_resources() from common device code. Hence
no need to have an explicit soc function to do the same.

TEST=lspci from kernel console shows same pci device list
without and without this patch.
