Subject: [PATCH] ARM: dts: am33xx: modify AM33XX_IOPAD for #pinctrl-cells = 2

Modify the AM33XX_IOPAD macro so that it works now that #pinctrl-cells =
<2>. The third parameter is just a zero and the pinctrl-single driver
will just OR this with the second parameter so it has no actual effect.

There are no longer any dts files using this macro (following my patch
to am335x-guardian.dts), but this will keep dts files not in mainline
from breaking.

Fixes: 27c90e5e48d0 ("ARM: dts: am33xx-l4: change #pinctrl-cells from 1 to 2")

NOTE:
checkpatch complains "Macros with complex values should be enclosed in 
parentheses" but all the other marcos in that section have the same
format so it seems appropriate to ignore checkpatch and maintain the
style.
