phaser: Enable EC_RST_ODL as wake source from PSL hibernate mode

This change enables EC_RST_ODL as wake source from PSL hibernate
mode. Since EC_RST_ODL does not need to be an interrupt during normal
EC operation, it is configured as GPIO_INPUT with wake on low-to-high
transition flag set to allow PSL common code to configure the input
pin correctly before going into PSL mode.

CQ-DEPEND=CL:1130853
BUG=b:109759558
BRANCH=None
TEST=Verified that phaser wakes up from PSL hibernate by toggling
EC_RST_ODL.
