Documentation: efi: emphasize watchdog deactivation on ExitBootServices ...

The UEFI specification paragraph quoted above notes:
> The watchdog timer is only used during boot services. On successful
> completion of ExitBootServices() the watchdog timer is disabled.

Thus disabling the watchdog is _the_ only proper behavior. Adjust the
wording accordingly.

Documentation: zii-imx7d-dev: Fix errors with openocd configuration script ...

When attempting to use the existing configuration file to bootstrap an
RMU2 board, openocd would consistently fail in the 'safe_reset' function
with a number of errors.

Disabling the internal reset handling (similar to what's done on the
i.MX7 Sabre boards) allowed barebox to download and run successfully.

Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac RMU2.

Documentation: zii-vf610-dev: Fix 'halt' in openocd configuration script ...

When attempting to use the existing configuration file to bootstrap
an SCU4 AIB board, openocd would consistently fail on the 'halt' command
with a "Target not examined yet" error.  Dumping target information
showed that vf610.cpu1 was the active target, rather that vf610.cpu0.

Adding a command prior to the halt to explicitly set the target core
resulted in proper operation.

Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac SCU4 AIB.

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.
