2018-06-15soc/intel/{glk,apl} and mainboards: Configure LPC_CLKRUN# pin as GPIO for S0ixHannah Williams
This pin does not have a native function for eSPI. Nonetheless if we use eSPI, it should be configured as a GPIO and kept unconnected to allow S0ix entry. Also removed initialization of LPC pins in mainboard code as they are already initialized in chipset code. The settings fpr LPC pins in chipset code were updated to those that were previously in mainboard code and have been validated on LPC flavor of Geminilake RVP. BUG=b:79251613 BRANCH=none TEST=From kernel prompt in bip, type powerd_dbus_suspend. Check on EC console that SOC enters S0ix.

2016-05-06soc/apollolake/lpc: Allow configuring SERIRQ via devicetreeAlexandru Gagniuc
Every other SOC uses a CONFIG_* flag to enable or disable SERIRQ continuous mode. Why they do that is beyond me, but the way we implement it on apollolake is via devicetree.
