soraka: update pad reset config of WLAN_PE_RST to RSMRST 

In skylake based platforms, setting GPIO pad reset config
to DEEP will reset the gpio configuration across warm reset,
set it to RSMRST to preserve the configuration across warm resets.
Also, moving the configuration from early to late as appropriate.

BUG=b:64386481
BRANCH=none
TEST= WiFi functionality across S3, DeepS3, S0ix and warm/cold reboot.
