In order to mx53 ROM to properly load the U-boot image, its header size should
be multiple of 512 bytes.
This issue was observed with gcc 4.6.2/4.7.3, which caused data aborts:

,and this patch fixes it.
Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

commit c73368150 (pmic: Extend PMIC framework to support multiple instances
of PMIC devices) introduced an extra 'retval' variable, but this is not
necessary since we have already the variable 'ret' in place.
So use 'ret' to store the return values from the pmic related calls and remove
'retval'.

The on-board number of available usdhc devices is something board
specific. The patch moves CONFIG_SYS_FSL_USDHC_NUM out of
mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd
board.
To keep the default mmc device for environment same as before (usdhc3),
it moves CONFIG_SYS_MMC_ENV_DEV out of mx6qsabre_common.h and changes
it to 1 for mx6qsabresd.

Support for a new command (defined at envs) - spl_export generates
the ATAGS image necessary for fast boot. Afterwards, it is stored
at ext4 partition.
Generated image format:
CRC [4B] SIZE [4B] PAYLOAD(ATAGS/DT) [SIZE]
Remarks:
- CRC is calculated only for PAYLOAD
- SIZE is the size of PAYLOAD
It is important to adjust ${splsize} when large image is generated.
It is defined as hex, since ext4 related commands expect it.
The ${spladdr} environment variable corresponds to
CONFIG_SYS_SPL_ARGS_ADDR
Additionally definitions for DFU have been refactored and support for
EFI has been added as well.

SPL doesn't write to the environment. These list entries prevent the
functions from being garbage-collected, even though nothing will look at
the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to
break due to size limitations and/or unresolved symbols.
A static inline function is used to provide a context in which we
can consume the callback, and thus avoid unused function warnings.
