[PATCH v4 0/2] pinctrl: single: support #pinctrl-cells = 2

Currently, pinctrl-single only allows #pinctrl-cells = 1.
This series will allow pinctrl-single to also support #pinctrl-cells = 2
If "pinctrl-single,pins" has 3 arguments (offset, conf, mux) then
pcs_parse_one_pinctrl_entry() does an OR operation on conf and mux to
get the value to store in the register.
To take advantage of #pinctrl-cells = 2, the AM33XX_PADCONF macro in
omap.h is modified to keep pin conf and pin mux values separate.
- v4: squash patches 2 and 3 together so that git biesct will not result
in a boot failure
- v3: change order of patches to make sure the pinctrl-single.c patch
does not break anything without the dts patches
- v2: remove outer parentheses from AM33XX_PADCONF macro as it causes a
compile error in dtc. I had added it per suggestion from checkpatch
about having parentheses around complex values.
