It really becomes a maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.
Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx23 client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

Instead of assigning SSP1_DETECT inside mmc0_4bit_pins_a, let the board dts
handle this setup.
Not every board will use MX23_PAD_SSP1_DETECT as SSP1 functionality.

The 8-bit mode mmc has pin conflicts with display. Let's use 4-bit
mode by default, so that display can be enabled together later.
Also add vmmc-supply for mmc device.

Add comments for pinmux-ids so that we do not have to keep looking at
Documentation/devicetree/bindings/pinctrl/fsl,mxs-pinctrl.txt to read
all these pinmux-ids.

Replace "gpmi" with "gpmi-nand" to get the
GPMI interface probing with DT instead of
failing to get clock.

It adds initial device tree support for imx23-evk board, and only
serial console is enabled.
