* power: skylake: Delay 10ms before deasserting PCH_RSMRST_Lstabilize-7199.BShawn Nematbakhsh2015-06-201-1/+17
| | | | | | | | | | | | | | | According to spec, RSMRST shouldn't be deasserted until 10ms after power signals become active. BUG=chrome-os-partner:41556 TEST=Manual on Glados. Verify that AP boots to S0 on power-on, goes to G3 on apshutdown, and back to S0 on powerbtn.

* skylake: Properly handle apshutdown when AP is already shutdownShawn Nematbakhsh2015-06-131-2/+4
| | | | | | | | | | | | | | | | If the AP is already shutdown, apshutdown would previously power the AP up with a power press. Fix this by making sure we're not already in G3 before triggering the power press. BUG=chrome-os-partner:40677 TEST=Run 'apshutdown' on glados while in G3, verify that AP does not power up.

* skylake: Use a simulated power button press to force-shutdown the APShawn Nematbakhsh2015-06-041-2/+13
| | | | | | | | | | | | | | | | Holding the power button is currently the best known way to bring the AP back to a state where it is shutdown and not powered. BUG=chrome-os-partner:40826, chrome-os-partner:40677 TEST=Run `apshutdown` on glados, verify that power state machine transitions to G3 after several seconds. Run `powerbtn`, verify that state machine transitions back to S0.

| | | | | | | | | | | | | | This change is necessary to ensure power-up of edge-case Skylake parts. BUG=chrome-os-partner:40677 TEST=Manual on Glados.

| | | | | | | | | | | | | | | | PCH_SLP_SUS_L can take up to 29ms to be deasserted after power-on or RTC reset. BUG=chrome-os-partner:40677 BRANCH=None TEST=Manual on glados.
