leds: leds-lp55xx: Support ENGINE program up to 128 bytes

Browse source

Some LED chip supports up to 16 pages and with some magic they can be
divided in 4 page for each ENGINE + 1 for each MUX. Following this we
can support bigger programs up to 128 bytes.

Rework the update_program_memory function to support program of multiple
pages instead of hardcoding it to one page per programs.
