backlight: jornada720: Minimise code duplication and handle errors better
Rickard Strandqvi's ran a code analysis application which found that jornada_lcd_get_contrast(() and jornada_lcd_set_contrast() contained some code duplication (calling the same functions during various code execution paths) and failed to return errors in a consistent manner. This patch aims to simplify the code, coercing it into behaving at a level expected of a driver in the Linux kernel.
