leds: Add driver for LT3593 controlled LEDs
The LT3593 is a step-up DC/DC converter designed to drive up to ten
white LEDs in series. The current flow can be set with a control pin.
This driver controls any number of such devices connected on generic
GPIOs and exports the function as as platform_driver.
The gpio_led platform data struct definition is reused for this purpose.
Successfully tested on a PXA embedded board.
