spl: dfu: add dfu support in SPL
Traditionally the DFU support is available only
as part 2nd stage boot loader(u-boot) and DFU
is not supported in SPL.
The SPL-DFU feature is useful for boards which
does not have MMC/SD, ethernet boot mechanism
to boot the board and only has USB inteface.
This patch add DFU support in SPL with RAM
memory device support to load and execute u-boot.
And then leverage full functionality DFU in
u-boot to flash boot inital binary images to
factory or bare-metal boards to memory devices
like SPI, eMMC, MMC/SD card using USB interface.
This SPL-DFU support can be enabled through
Menuconfig->Boot Images->Enable SPL-DFU support

<asm-generic/...> is supposed to be included from <asm/...> when
arch-headers fall back into generic implementation. Generally, they
should not be directly included from .c files.
Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>. Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

Makefile: rm u-boot.cfg dependencies are missing
Prior to the previous patch, a freshly created .u-boot.cfg.cmd may not
correctly represent all dependencies for u-boot.cfg. The previous change
only solved this issue for fresh builds; when performing an incremental
build, the deficient .u-boot.cfg.cmd is already present, so u-boot.cfg
is not rebuilt, and hence .u-boot.cfg.cmd is not rebuilt with the correct
content.
Solve this by explicitly detecting when the dependency file .u-boot.cfg.d
has not been integrated into .u-boot.cfg.cmd, and force u-boot.cfg to be
rebuilt in this case by deleting it first. This is possible since
if_changed_dep will always delete .u-boot.cfg.d when it executes
successfully, so its presence means either that the previous build was
made by a source tree that contained a Makefile that didn't include the
previous patch, or that the build failed part way through executing
if_changed_dep for u-boot.cfg. Forcing a rebuild of u-boot.cfg is required
in the former case, and will cause no additional work in the latter case,
since the file would be rebuilt anyway for the same reason it was being
rebuilt by the previous build.

Makefile: use if_change_dep for u-boot.cfg

This results in Kbuild not knowing about which files u-boot.cfg depends

A practical result of this is that u-boot.cfg may continue to reference
CONFIG_ options that no longer exist in the source tree, and this can
cause the adhoc config options check to fail.
This change modifies Makefile to use if_changed_dep, which in turn causes
