leds-lp55xx: add new lp55xx_register_sysfs() for the firmware interface
LP55xx family chips have internal program memory which run various patterns.
Using this memory, LEDs continue on blinking/dimming without continuous I2C
commands. That means the I2C HOST can be entered into sleep once the memory
is updated.
An application can get hex data from a file and write them into
the program memory through the I2C. This is general firwmare interface.
This patch is the initial step for adding the firmware interface.
