icelake: Cleanup power sequencing for IceLake/TigerLake/JasperLake
Configure PWROK generation related signals for Ice Lake, Tiger Lake, and
Jasper Lake SoCs. The array driven sequencing provides better
flexibility for the PWROK signals, some of which may be automatically
handled by the platform and some require EC control.
BUG=b:150726713
BRANCH=none
TEST=make buildall
TEST=Volteer: verify VCCIN enable and SYS_PWROK generation during S0 and
verify signals are deasserted when exiting S0.
TEST=Wadledoo: verified 2ms delay between ALL_SYS_PWRGD and PCH_PWROK,
verified JPL sequences to S0.
