Revert "spring: always enable the PP3300_WWAN rail"
This reverts commit 154c73f32d2625d2cfbe2fa9be4e15b4f382a917.
The kernel driver to control TPS65090 FETs is now submitted in our tree,
and turning on the FET3 connected the 3G modem by default.
So let's remove the hardcoded to allow better power management policy on
the CPU side.

BRANCH=spring
BUG=chrome-os-partner:17790
TEST=on Spring, boot and dump the TPS65090 configuration from the EC
command line by using "pmu" command.
See 0x1f in the register 0x11 for FET3.
