Add DDR support for eMMC 4.4 cards.
Currently the clock is set to 40Mhz to get good compatibility.

Due the ROM code bug, we need to let clock of mx35 esdhc always on
or the HW reset may not work.

Add a control flag for clock always on function in plat_data.
By default ,esdhc clock will be automatically gate off by HW
if there's no CMD/DATA transferring.
This inferface allows user to easily disable clock auto gate off
according specicial using cases such as SDIO card that needs
clock to send SDIO interrupt signal to host.

Add dll override mode enable and the number of delay cells flag
in platform_data.
This allows user to regulate clock delay line in platform specific code
according to different board and cards.

Leaving EPDC AXI enabled is bad for power management. EPDC/Display
clks must be enabled before clock rate can be set. We must then disable
these clocks before completing init.

As MX5x one image kernel, the v4l2 driver is also configured in MX508.
This causes v4l2 capture module insert or bootup with builtin crash.
Now move all the v4l2 output, capture devices structure and registeration
into MSL code. The SoC who does not have CSI, will not have v4l2 device
registered anymore.
Rename the device name to mxc_v4l2_output and mxc_v4l2_capture.

Change mx53 EVK and Armadillo2 iomux to use iomux-v3.
- Creates iomux-mx53.h to defines IOMUX pins for MX53 HW

HW
- Moves pin structure and functions that were in

We're keeping mx51_pins.h because the MX51-3DS support will

To better align Freescale's BSP to kernel.org, it is
better to use iomux-v3 instead of mxc_iomux.
Change mx50 iomux to use iomux-v3.

- Moves pin structure and functions that were in
mx50_arm2_gpio.c into mx50_arm2.c and deletes

mx23/mx28 otg port host mode will not enable internal
phy clock (portsc1 PHCD1), in that case, if the user loads
the gadget firstly, then, unloads the gadget module.
The host will not work due to gadget disable internal
phy clock after its unload process, but host doesn't enable it
at its initialization.
This fix will add enable internal phy clock at otg initialization process,
and disable it at de-initialization process.

A better way to check for devices that support USB remote

1. Adjust VDDGP for 1GHZ as 1.15v
2. Adjust VDDGP for 800MHZ as 1.05v
3. Not all current MX53 boards can run up to 1GHZ. So one limitation is
added into clock.c to limit 1GHZ working point. To enable 1GHZ
working point in kernel, please increase the GP voltage and type the
command "clk core 1000" in uboot console to switch CPU core to 1GHZ.
This limitation will be removed after all boards support 1GHZ.
