SPEAr: Remove existing padmux support for SPEAr
We must use pinctrl framework instead of defining per SoC pinmux drivers. This patch removes existing padmux support present for SPEAr platform. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Stephen Warren <swarren@wwwdotorg.org>
