[U-Boot] [PATCH v2 1/4] dfu: Drop unused prototype of dfu_trigger_reset()

[Andy Shevchenko]

After the commit 1cc03c5c53c0 ("dfu: Provide means to find difference between
dfu-util -e and -R") the dangling ptototype appeared. Remove it here.

[U-Boot] [PATCH v2 2/4] dfu: Refactor do_dfu() to handle optional argument

[Andy Shevchenko]

In the future we may utilize optional argument in 'dfu' command line.
As a preparation for this, refactor do_dfu().

[U-Boot] [PATCH v2 3/4] dfu: Add optional timeout parameter

[Andy Shevchenko]

When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.

This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.

The patch is based on the commit
https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c
by Sebastien Colleur, which has been heavily reworked due to U-Boot changes
in the past.

Can this all use

   if (IS_ENABLED(CONFIG_DFU_TIMEOUT))

to reduce the number of #ifdefs?

Also I wonder if CONFIG_VAL(...) returns 0 if the CONFIG doesn't
exist? If so, you might be able to remove all the #ifdefs and use 0 as
the value that means infinite?
