qcom: Move enabling/disabling 3.3V rail to the board level
In the next generation, the 3.3V rail is not controlled by EC anymore.
Move the control logic to the board level. The 3.3V rail should be
enabled before the power on sequence, so use the hook chipset pre-init
hook. Disable it on the chipset shutdown complete hook.
For Trogdor, do it on the baseboard level.
For Herobrine, do it on the board level, Herobrine-NPCX7, only.
Herobrine-NPCX9 and other future boards don't need it.
BRANCH=None
BUG=b:187980397, b:192253134
TEST=Tested the Lazor EC-OS and Zephyr images and booted to AP.
TEST=Tested the Herobrine-NPCX7 EC-OS and Zephyr images and booted to AP.
