[PATCH 12/17] power: supply: cros: Use cros_ec_send_cmd_msg()

From: Prashant Malani
Date: Thu Jan 30 2020 - 15:35:21 EST


Replace cros_usbpd_charger_ec_command() with cros_ec_send_cmd_msg()
which does the same thing, but is defined in a common location in
platform/chrome and exposed for other modules to use. This allows us to
remove cros_usbpd_charger_ec_command() entirely.
