The current code was implemented with some default configurations,
this default configuration works on board and doesn't work on other.

This patch accepts the configuration through platform data and configures
the encoder depending on the data set.

Can you add a short description for struct adv7343_power_mode? It's
sufficient to point to the relevant section in the datasheet (add a url
or something like that).
