leds-lp55xx: use lp55xx common init function - post int
LP5521/5523 chip configuration is replaced with lp55xx common function,
lp55xx_post_init_device().
Name change:
lp5521/5523_configure() to lp5521/5523_post_init_device()
These are called in init function.
Register access function
Argument type is changed from 'i2c_client' to 'lp55xx_chip'.
Use exported R/W functions of lp55xx common driver.
Temporary variables in lp5521/5523_init_device()
These functions will be removed but temporary variables are needed for
blocking build warnings - incompatible pointer.
