[PATCH] ns2: Fix off by one bugs in ns2_pinmux_enable()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The pinctrl->functions[] array has pinctrl->num_functions elements and
the pinctrl->groups[] array is the same way.  These are set in
ns2_pinmux_probe().  So the > comparisons should be >= so that we don't
read one element beyond the end of the array.

Fixes: b5aa1006e4a9 ("pinctrl: ns2: add pinmux driver support for Broadcom NS2 SoC")
