While some support is still missing (USB, LCD), we already have some
prerequisites in place like USB PHY and PWM (for backlight). We also have
gained one new board and some other new drivers since the last time the
defconfig was touched, so enable them all, as well as some possibly useful
commands.

Some distributions might not have python in /usr/bin, but in $PATH.
Using #!/usr/bin/env python solves this, and is consistent with how the

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.

On some machines the python command is provided by Python 3 while on
most (at least in my bubble) it is still Python 2. Modify the code to
make it usable by both Python versions.
print_function is available in __future__ since Python 2.6.0a2, which
shouldn't be a relevant restriction.
The modified script generates the same documentation as the old one;
independent if the script is called using Python 2 (here: 2.7.16) or
Python 3 (here: 3.7.3).

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.

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.
