When the kernel load address is chosen by the user/image we need
to check if the kernel needs to relocate itself before decompression.
If that's the case the spacing behind the kernel must allow for this
relocation without overwriting anything placed behind the kernel.

This fixes:
0a37e22d (bootm: use names instead of numbers for image parts)
This commit switches to strings for the image numbers for better FIT
image support (which uses names instead of numbers). These strings
may be NULL when no image number is given. They are used uninitialzed
in several places. Introduce a wrapper function to convert the string
into a number. Check for NULL here in which case we return 0 which
is the correct value.

PHY like the ks8721bl used on the edb9302 and similar evaluation boards
will initially not respond to the ep93xx_phy_read/write functions when
the MII-preamble is supressed. The supression is switched on by default
and must be switched off by clearing bit 8, see also EP93xx Users guide.
Removing the orphaned MII_SUPPRESS_PREAMBLE config option, note:
setting MII_SUPPRESS_PREAMBLE would actually enable the preamble transmission.

dev_request_mem_region returns a void * which shall be checked with
IS_ERR(), but in some cases the valid pointer returned clashes with
error values. This is especially the case on some Atmel SoCs.
This introduces dev_request_mem_resource which returns a struct resource
instead which in any case can be checked with IS_ERR(). It's the drivers
responsibility then to get the IOMEM pointer from the resource.

Currently all fastboot flash commands with UBI images are handled by a
final call to 'ubiformat'. This only makes sense for flash commands
where the target file is a mtd device. If we just want to transfer a UBI
image we would expect a simple copy to the correct location.
This patch checks if the destination file is a MTD device by opening it
and calling an ioctl MEMGETINFO. Only for MTD devices, ubiformat is
called.

DualLite/Solo. After that change they are SoM specific. They match only
