backlight: fix broken regulator API usage in l4f00242t03
The regulator support in the l4f00242t03 is very non-idiomatic. Rather than requesting the regulators based on the device name and the supply names used by the device the driver requires boards to pass system specific supply names around through platform data. The driver also conditionally requests the regulators based on this platform data, adding unneeded conditional code to the driver. Fix this by removing the platform data and converting to the standard idiom, also updating all in tree users of the driver. As no datasheet appears to be available for the LCD I'm guessing the names for the supplies based on the existing users and I've no ability to do anything more than compile test. The use of regulator_set_voltage() in the driver is also problematic, since fixed voltages are required the expectation would be that the voltages would be fixed in the constraints set by the machines rather than manually configured by the driver, but is less problematic.
