cover ARM: digicolor: add pinctrl support

Hi ARM SoC maintainers,

This series enables the Conexant Digicolor CX92755 pinctrl driver. The driver itself was merged during the v4.3 cycle in commit 38b0e5071eca (pinctrl: driver for Conexant Digicolor CX92755 pin mapping)

Please consider for v4.4.

Thanks,
baruch

Applied to next/soc, but please add a patch description even for trivial patches like this in the future. A good changelog text here would explain why this wasn't done in the past but is necessary now.

Thanks,
