platform/x86: x86-android-tablets: Add an init() callback to struct x86_dev_info
Add an init() callback to struct x86_dev_info, board descriptions can use
this to do some custom setup before registering the i2c_clients, platform-
devices and servdevs.
Also add an exit() callback to also allow for cleanup of the custom setup.
