pinctrl: msm: Correct interrupt code for TLMM v2
Acking interrupts are done differently between on v2 and v3, so add an extra attribute to the pingroup struct to let the platform definitions control this. Also make sure to start dual edge detection by detecting the rising edge. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
