pinctrl: move strict option to pinmux_ops
While the pinmux_ops are ideally just a vtable for pin mux calls, the "strict" setting belongs so intuitively with the pin multiplexing that we should move it here anyway. Putting it in the top pinctrl_desc makes no sense. Cc: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
