[PATCH] ARM: LPC32xx: Adjust dts files to gpio dt binding

[PATCH] ARM: LPC32xx: Adjust dts files to gpio dt binding

[Roland Stigge]

The GPIO devicetree binding in 3.5 doesn't register the various LPC32xx GPIO
banks via DT subnodes but always all at once, and changes the gpio referencing
to 3 cells (bank, gpio, flags). This patch adjusts the DTS files to this
binding that was just accepted to the gpio subsystem.

Applies to branch next/dt of arm-soc.git

Thanks, applied to fixes for 3.5.
