Subject: [PATCH v2] Input: tm2-touchkey - use LEN_ON as boolean value
 instead of LED_FULL

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.
