ARM: EXYNOS: Add generic PWM lookup support for SMDKV310
Generic PWM framework requires that the board setup code register a static mapping that can be used to match PWM consumers to providers. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Reviewed-by: <thierry.reding@avionic-design.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
