When using the board files the LCD works, but not with the DT.
This adds enables the original da850-evm to work with the same
LCD in device tree mode.

The EVM has a gpio for backlight regulator and a PWM for dimming
the backlight.  The LCD and the vpif display pins are mutually

In order GPIOS from this controller to be used with the "gpio-hogs"
property, the tca6416 node has to properly labeled as a gpio-controller,
and use #gpio-cells.

With that, the SEL_A, SEL_B, SEL_C lines that are used to select VPIF
input can be configured using GPIO hogs.

As an example, example, the configuration below selects the analog video
input on the da850-evm UI board:

&tca6416 {
	 status = "okay";

	 sel_a {
		gpio-hog;
		gpios = <7 GPIO_ACTIVE_HIGH>;
		output-high;
		line-name = "ADC_ENn";
	 };
	 sel_b {
		gpio-hog;
		gpios = <6 GPIO_ACTIVE_HIGH>;
		output-high;
		line-name = "CAMERA_ENn";
	 };
	 sel_c {
		gpio-hog;
		gpios = <5 GPIO_ACTIVE_HIGH>;
		output-low;
		line-name = "VIDEO_IN_ENn";
	 };

Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.

This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

Currently the davinci da8xx boards use the mach-davinci aemif code.
Instantiating an aemif node into the DT allows to use the ti-aemif
memory driver and is another step to better DT support.
This change adds an aemif node in the dtsi while retiring the nand_cs3
node. The NAND is now instantiated in the dts as a subnode of the aemif
one along with its pins.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.

Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */
