zephyr: add support for ln9310 driver
Add Kconfig option for enabling the LN9310 switched capacitor
converted used on Lazor. This is a dependency of the SC7180 power
sequencing for Lazor (other trogdor boards will have differing
switched capacitor drivers).
BUG=b:183054226
BRANCH=none
TEST=compile with LN9310 driver on lazor (follow-up CL)
