mb/google/brya/variants/crota: fine tune WWAN power sequencing
Because the poweron state of some of the WWAN GPIOs is the
asserted state, this patch fixes the poweron sequence so that the
WWAN module is always correctly powered on, in both cold and warm
reboot scenarios.
BUG=b:233564770
TEST=USE="project_crota emerge-brya coreboot" and verify it builds
