Add a gdb script with two helper functions which use the new
pbl_barebox_break symbol to calculate the current barebox load address
on the device and loads a barebox ELF file to this address.

Documentation: zii-vf610-dev: Add necessary post reset delay ...

As observed on CFU1 board, without this delay we interrupt mask ROM
code execution even before it sets up any PLLs correctly preventing
Barebox from correctly starting up. Fixing this by adding PLL setup
code to OpenOCD script helps somewhat and Barebox starts, howerver CPU
started this way ends up being unstable crashing randomly during
further Barebox use.

Adding a simple 100 ms post reset delay resolves all of the described
issues. This is also consistent with how other ZII boards are set up.

Documentation: user: suggest U-Boot's bootm, not go ...

Unlike barebox, U-Boot's go command doesn't have any provisions
for cache handling and as such, bootstrapping barebox via go can
cause stale data to be erroneously executed as instructions.

The official documentation[1] suggests use of bootm instead, which
does the necessary flushing and invalidation. Update our documentation
accordingly.

Add a driver to expose U-Boot environment variable data as a single

    * Read/write logic in presence of redundant partition

Not very useful on its own, it is a crucial low-level plumbing needed
by filesystem driver introduced in the following commit.
