spring: always enable the PP3300_WWAN rail
The kernel driver to control the 3G modem LDO is not submitted yet.
Let's hardcode it for now to enable RF testing and revert this patch
later.

BRANCH=none
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.
