ARM: i.MX: xload-esdhc: Allow custom buffer address, device offset ...

Add code to support specifying different buffer address and SD/MMC
device offset to read it from in esdhc_start_image(). This change is
needed to support i.MX8.

NOTE: We intentionnaly "emulate" reading at arbitrary offset in
esdhc_start_image() as opposed to implementing it in
esdhc_read_blocks() in order to avoid having to detect if units of
blocks or bytes should be used to specify offset to CMD18.

ARM: i.MX: xload-esdhc: Rework to make code be less i.MX6-specific ...

Convert imx6_esdhc_start_image() into a generic esdhc_start_image() by
making accept already filled "struct esdhc" as well as use
esdhc_read_blocks().

With that change, create new imx6_esdhc_start_image() whose sole task
is to properly fill a struct esdhc with appropriate offset and to pass
it on to esdhc_start_image().

Both changes are made with a goal of simplifying adding support of new
SoC in mind (see following commits adding support for i.MX8 as example).

NOTE: This commit does not re-implement imx6_esdhc_load_image(),
instead opting for dropping it, due to lack of any users in the
codebase.

omap/am33xx_bbu: use file_write_flash() instead of its own variant ...

There are two differences between file_write_flash() and write_image()
(which is removed in this patch):

 - file_write_flash() uses write_full() vs. write() in write_image()
 - file_write_flash() doesn't erase the whole device but only the needed
   space

So the new code should be more robust and maybe even faster.
