Subject: [PATCH v2 1/3] ARM: dts: change AM33XX_PADCONF macro separate conf and mux

AM33XX_PADCONF macro is modified to keep pin conf and pin mux separate.

This requires #pinctrl-cells = 2 in am33xx-l4.dtsi

pinctrl-single.c but also be changed to support "pinctrl-single,pins"
with 3 arguments (offset, conf, mux)

Signed-off-by: Drew Fustini <drew@...gleboard.org>

v2 change:
- 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.
