2015-11-13intel/skylake: ensure the RTC time is setAaron Durbin
In 2014 or so the RTC code was changed to assume the ALTCENTRY register (0x32) as always being utilized for creating an rtc_time. However, one needs to ensure it's set at least once otherwise the year field in rtc_time is not sane. In practice this doesn't matter unless somone wants to use the full year value. cmos_init() should do the same thing in the rtc fail case, but the machine I had never had that set correctly. BUG=chrome-os-partner:47388 BRANCH=None TEST=Booted glados w/ 0xff ALTCENTRY value. New value is 0x20.

2015-08-14skylake: remove ec_smi_gpio and alt_gp_smi_enAaron Durbin
The ec_smi_gpio and alt_gp_smi_en devicetree options are goign to be removed. The plan for skylake is to set the settings by the mainboard through either gpio pad configuration or through helper functions. Moreover, these values only allow *1* SMI GPIO configuration in that the following has to be true: alt_gp_smi_en = 1 << (ec_smi_gpio % 24) If not, then another gpio(s) from the same group has the SMI_EN bit set for it. Lastly, remove all the subsequent dependencies as they are no longer used: enable_alt_smi() and gpio_enable_group().

2015-08-14skylake: provide GPE0 routing devicetree configurationAaron Durbin
On skylake the GPE0 routing can be dynamically changed to a particular GPIO group. Provide the ability for the mainboard to set the route accordingly. If any of the values in the devicetree are the same the current setting in the PMC register is used. The GPIO communities need to have matching configuration for the plumbing to work properly. BUG=chrome-os-partner:43778 BRANCH=None TEST=Built and booted glados w/ and w/o devicetree changes. Fields are set accordingly.

2015-08-14skylake: clear write-1-to-clear fields in power regsAaron Durbin
Explicitly clear all write-1-to-clear fields in the appropriate power state registers. That way stale state isn't left around from boot to boot. The MMIO PMC registers are always added such that the resource can be accessed from reg_script. It doesn't hurt to add the resource, and it's actually more informative by attaching the actual resources owned by the device. BUG=chrome-os-partner:43625 BRANCH=None TEST=Built and boot glados. Did global reset. Noticed bits set. Did normal reset and saw those same bits no longer set.
