mb/google/brya: change reset signal for GPP_F17 from PLTRST to DEEP 

PCH_INT_ODL (GPP_F17) is used to wake AP from S3, however it was configured
to reset state on PLT reset assertion. This change reconfigures the pad
using DEEP instead of PLTRST to retain pad configuration across S3.

BUG=b:178545523
TEST=manual: verified that asserting PCH_INT_ODL wakes system and the wake
source is GPP_F17
