On mx23 the pad voltage selection bit needs to be always '0', since '1' is a
reserved value.

For example:

Pin 108, EMI_A06 pin voltage selection:
0= 1.8V (mDDR) or 2.5V (DDR1);
1= reserved.

Fix the pad voltage definitions for the mx23 case.

Implement BOOT_OFFSET command for imximage. This command is parallel
to current BOOT_FROM command, but allows more flexibility in configuring
arbitrary image header offset. Also add an imximage.cfg with default
offset values into arm/arch/imx-common/ so the board-specific imximage.cfg
can include this file to avoid magic constants.

The syntax of BOOT_OFFSET command is "BOOT_OFFSET <u32 offset>".

PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.

By the way, remove some unused pad control definitions.

There is no change of behavior.

Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

Commit dc88403e "iomux-v3: Place pad control definitions into common file" broke
mx51_efikamx because it made i.MX6's pad control definitions conflict with
i.MX51's.

i.MX51's pad control definitions are actually common to some other i.MX
(25/35/53), so move them to the common iomux-v3.h (just like what is done in
Linux's), and select the correct definitions depending on whether CONFIG_MX6 is
defined or not.

The MX23 Boot ROM does blindly load from 2048 offset while the MX28
does parse the BCB header to known where to load the image from. We
move the BCB header to 4 sectors offset so same code can be used by
