soc/intel/skylake: Control fixed IO decode from devicetree
The current implementation doesn't allow custom values for the LPC IO
decodes and IO enables.
Add the lpc_ioe and lpc_iod values. If they are not zero, they will be
used instead of the current handling for COMA and COMB.
BUG=N/A
TEST=tested on facebook monolith
