leds: leds-lp3944.h - remove unneeded includes

These were needed in the first version of the driver because we used to expose
workqueue and led class details in the header file, now we don't.

This helper chip can drive up to 8 leds, with two programmable DIM
modes; it could even be used as a gpio expander but this driver assumes
it is used as a led controller.

The DIM modes are used to set _blink_ patterns for leds, the pattern is
specified supplying two parameters:
- period: from 0s to 1.6s
- duty cycle: percentage of the period the led is on, from 0 to 100

LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
leds, the camera flash light and the displays backlights.
