Add the necessary nodes to enable the LCD controller and the
LCD panel that is attached to the Texas Instruments AM335x
EVMSK platform. Also setup the necessary pin mux within the
DT file to drive the LCD connector and add the correct
pinmux settings for the lcd pins to be configured to when
the SoC goes into sleep state for the minimum power
consumption.
For the sleep mode LCD pin settings, MUX_MODE7 is chosen as
this corresponds to switching the pins into input GPIO's with
an internal pulldown. Which has been determined to offer the
lowest power solution vs leaving the pins configured in LCD
mode.

Tony, Benoit,
I didn't see this patch get applied anywhere, so I updated it and I am
resending it. Please let me know if you need any more info before you will
apply it.
Thanks, Darren
v3:
Updated subject to match classification style of subsystem
Rebased against 3.16-rc3
v2:
Fixed up the incorrect label ordering in the pinmux comments for LCD pins
16 through 23 as reported by Wolfram Sang <wsa@sang-engineering.com>

Tomi, do you want to ack this one or want to queue the panel .dts
changes into a separate branch?

I don't really have experience with the LCDC used on AM335x SoC (it
