[PATCHv2] pinctrl: exynos: Add support for Exynos4415

[Chanwoo Choi]

From: Tomasz Figa <tomasz.figa at gmail.com>

The pin controllers of Exynos4415 are similar to Exynos4412, but certain
differences cause the need to create separate driver data for it. This
patch adds pin controller and bank descriptor arrays to the driver to
support the new SoC.
