Roshan Pius a26a6e0807 wifi: Add firmware mode controller
This module will make the necessary calls to reconfigure the
driver/firmware in the required state.
The module assumes that the sysfs paths needed to be accessed has been
chowned to "wifi" at bootup in the device's .rc file.

Bug: 32018162
Test: Compiles
