    broadwell: Add support for ACPI \_GPE._SWS
    
    In order to report the GPE that woke the system to the kernel
    coreboot needs to keep track of the first GPE wake source and
    save it in NVS so it can be returned in \_GPE._SWS method.
    
    This is similar to the saving of PM1 status but needs to go
    through all the GPE0_STS registers and check for enabled and
    triggered events.
    
    A bit of cleanup is done for areas that were touched:
    - platform.asl was not formatted correctly
    
    BUG=chrome-os-partner:8127
    BRANCH=samus,auron
    TEST=manual:
    - suspend/resume and wake from EC event like keyboard:
    ACPI _SWS is PM1 Index -1 GPE Index 112  ("special" GPIO27)
    - suspend/resume and wake from RTC event:
    ACPI _SWS is PM1 Index 10 GPE Index -1  (RTC)
    - suspend/resume and wake from power button:
    ACPI _SWS is PM1 Index 8 GPE Index -1
    - suspend/resume and wake from touchpad:
    ACPI _SWS is PM1 Index -1 GPE Index 13
    - suspend/resume and wake from WLAN:
    ACPI _SWS is PM1 Index -1 GPE Index 10
