leds-lp55xx: code refactoring on selftest function
LP5521 and LP5523 have a selftest function which is run via the sysfs. Use lp55xx driver data and R/W functions rather than lp5521/5523 private data and functions. Additionally, if-statements are changed for code simplicity. Unused functions, lp5521/5523_read() are removed.
