Move display timing configurations into device tree, so that the

Put the clock to the devicetree, so the driver can take care of it
later. Then, we don't have to do the enabling as a workaround in board
init.

[shawn.guo: add enet_out into imx28.dtsi and overwrite it for m28evk]
Signed-off-by: NShawn Guo <shawn.guo@linaro.org>

Slow down the I2C clock speed on M28 and SPS1 as it turns out the
I2C block in i.MX28 can not operate stable enough with the bus
running at 400kHz. Note that the driver used by Freescale runs
the bus at 250kHz when 400kHz speed is selected, but the mainline
Linux kernel runs the bus at actual 400kHz and that's where it is
occasionally unstable. Play safe and run the bus at 100kHz.

Update the mach-mxs machine by removing the enet_clkout(). The new
revision of the board doesn't need that. Also, update the DTS file
with all the new drivers pulled in the mainline recently, that is,
SPI, LRADC, USB.

hog_pins is used to setup the pin functions, and it is not neccesarily used only
for GPIO pins, so use only 'hog' to describe a more generic term.

Rename mxs dts files with soc name being the prefix, so that the board
dts file can be located easily by soc name, and we also gain the
consistency of naming.

Add vmmc-supply for mmc device, so that the power to mmc slot can be
turned on by mmc driver if bootloader hasn't done it.

Also remove "okay" status for mmc1/ssp1, as the device has pin conflict
with gpmi-nand.  Actually the device is already disabled since the
mxs-mmc driver adopts pinctrl support because there is no pinctrl setup
for the device in dts.  Make this explicit by removing "okay" status.
