Subject: [PATCH 1/1] pinctrl: samsung: Group all drivers in a sub-dir

Group all pin control drivers of Samsung platform together in
a sub-directory for easy maintenance.

Signed-off-by: Sachin Kamat <sachin.kamat@...sung.com>
---
This patch has been inspired by a similar patch [1] from Linus Walleij for
Qualcomm drivers. I have boot tested this patch on Exynos boards and
compile tested for other Samsung platforms.
