soc/intel/skylake: add option to statically clock gate 8254 timer
In order to save more power by shutting down clocks add the
ability to optionally clock gate the 8254 programmable interrupt
timer. When doing this the platforms lose their "PC"-ness which
certain payloads and OSes rely on such as SeaBIOS.
BUG=chrome-os-partner:50214
BRANCH=glados
TEST=Enabled option on chell. Noted the bit is set upon booting.
