mb/google/nissa/var/uldren: Modify WWAN power sequence
Follow spec[1] to modify WWAN power sequence. The WWAN power sequence
of warm reset is fail. The correct sequence is WWAN_EN should keep high when doing warm reset. Set GPP_D6 to PWROK which is not to do PAD
reset when warm reset.

BUG=b:285065375
BRANCH=firmware-nissa-15217.B
TEST=1. emerge-nissa coreboot chromeos-bootimage
2. power sequence meets spec.
