zephyr: Add support for setting charger sense-resistors
We need a different value for lazor, so move this to Kconfig. We may at
some point move this to device tree.
BUG=b:183296099, b:175881762
BRANCH=none
TEST=with other CLs, build zephyr for lazor and see that the option is
present
build config for volteer and make sure it has not changed
