[3/3] mfd: cros_ec: Add charge state control cell

Commit Message

Sung-Chi Li Nov. 18, 2024, 9:33 a.m. UTC

The driver of controlling the charge chip connected on the ChromeOS
Embedded Controller (EC) is added in the commit "platform/chrome:
cros_ec_charge_state: add new driver to control charge". To register
the charge state sub-devices, add mfd cells in the cros-ec-dev mfd
driver, and register charge state sub-devices based on whether the EC
supports battery feature.
