Previously, the statement looked like:

    slpm[x] &= ~BIT(g->grp.pins[i]);

Where:
 - slpm is a unsigned int pointer;
 - g->grp.pins[i] is a pin number. It can grow to more than 32.

The expected shift amount is a pin bank offset.

This bug does not occur on every group or pin: the altsetting must be
NMK_GPIO_ALT_C and the pin must be 32 or above. It might have occured.
For example, in pinctrl-nomadik-db8500.c, pin group i2c3_c_2 has the
right altsetting and pins 229 and 230.

Patch applied!

Since the bug is not affecting the deployed UX500 systems I have merged
it with the rest as non-urgent fix, but it can be backported as a standalone
patch if the stable maintainers want it after the release of v6.9-rc1.

Yours,
Linus Walleij
