We need to access I2C bus when switching brightness, and that may block,
therefore we have to set stmfts_brightness_set() as LED's
brightness_set_blocking() method.

Not all devices use the same keycodes in the same order,
so add possibility to define keycodes for buttons present
on actual hardware.
If keycodes property is not present, we assume that device has
at least MENU and BACK keys.

tm2-touchkey doesn't have brightness levels, but only on/off states,
so replace LED_FULL with LED_ON.

The touchkey on midas boards is almost identical.
The only real difference is that it uses the same register for both
keycode and base.

Commit 4e552c8cb5bc ("leds: add LED_ON brightness as boolean value")
has introduced the LED_ON enumeration value that can be used
instead of LED_FULL which has more of a linear value.
Because the tm2-touchscreen doesn't have brightness levels, but
it's a simple on/off led, use LED_ON instead of LED_FULL.

If there is no call to dev_get_drvdata() or input_get_drvdata(),
the call to input_set_drvdata() is unnecessary and can be dropped.

This patch adds support for the TM2 touch key and led functionality.
The driver interfaces with userspace through an input device and reports
KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by
"/sys/class/leds/tm2-touchkey/brightness".
