pinctrl: renesas: rza1: Normalize return value of gpio_get()

Browse Source 
The GPIO .get() callback is expected to return 0 or 1 (or a negative
error code).  Ensure that the value returned by rza1_gpio_get() is
normalized to the [0, 1] range.

Fixes: 86ef402d80 ("gpiolib: sanitize the return value of gpio_chip::get()")
