zephyr: add support for switchcap in device tree
This commit adds support for switchcap definition in device tree.
It will allow to remove board specific files which implemented
the switchcap functionalities. This will unify the logic between
different board in zephyr.
BRANCH=main
BUG=b:194211207
TEST=Use linked TEST commits to see example of definitions for lazor
Use GPIO or LN9310 version, build and flash to lazor.
Board should be able to boot correctly.
