[PATCH] pinctrl: mediatek: Fix some off by one bugs

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

These comparisons should be >= instead of > to prevent accessing one
element beyond the end of the hw->soc->pins[] array.

Fixes: 3de7deefce69 ("pinctrl: mediatek: Check gpio pin number and use binary search in mtk_hw_pin_field_lookup()")
