misc: panel: Abstract temporary backlight handling
Currently the periodic scan timer is used for three purposes,
entangling keypad and display handling, which are both optional:
1. Scanning the keypad,
2. Flashing the backlight when a key is pressed,
3. Disabling temporary backlighting after a fixed period of time.
Abstract the second purpose using a new lcd_poke() function.
Make the non-periodic temporary backlight handling independent from
keypad handling by converting it to a delayed workqueue.
