[PATCH 1/2] leds: lp55xx: handle enable pin in driver

* Sebastian Reichel [off-list ref] [131022 06:02]:

This patch moves the handling of the chip's enable pin from the board
code into the driver. It also updates all board-code files using the
driver to incorporate this change.

This is needed for device tree support of the enable pin.

This seems safe to merge along with the other LED patches, the
changes to arch/arm/mach-omap2 should not conflict with anything.

So for the arch/arm/mach-omap2 changes:
