Trogdor: Disable PSL mode hibernate
The RTC stops counting under PSL mode. The Trogdor design relies on
EC to give the RTC counter. Disable the PSL mode hibernate and use
the traditional non-PSL mode way, i.e. power down all RAM blocks
except the last one.
BRANCH=None
BUG=b:169595541
TEST=Tested on Lazor; triggered hibernate, and waked it up using:
* power button press
* lid open
* servo toggling EC_RST_ODL
* AC plug (doesn't work, need to investigate why)
TEST=Verified RTC still counting in hibernate:
