broadwell: Fixes for _SWS support
- These should be 64bit values so when they try to return -1 it is interpreted properly by the kernel. - The GPE value needs to be reset at the start so it does not return stale data from a previous resume. - If a GPE register is zero the value should only be updated if it has not yet found a set bit. BUG=chrome-os-partner:34532 BRANCH=samus,auron TEST=build and boot on samus, suspend/resume with various wake sources and ensure the reported _SWS values are correct in every case.
