drivers/leds/leds-lp5521.c: add 'update_config' in the lp5521_platform_data

Browse source 
The value of CONFIG register(Addr 08h) is configurable.  For supporting
this feature, update_config is added in the platform data.  If
'update_config' is not defined, the default value is 'LP5521_PWRSAVE_EN |
LP5521_CP_MODE_AUTO | LP5521_R_TO_BATT'.

To define CONFIG register in the platform data, the bit definitions were
mo= ved to the header file.

Documentation updated : description about 'update_config' and example.
