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.
