There's a clear mismatch between actual TCL code and comment right
next to it. Comments are definetly right, so fix the TCL code.
Fixes: 02738f4b59 ("Documentation: zii-vf610-dev: Reconcile DDR setup with DCD")

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.

Fix a buggy while loop expression, that, due to '==' operator's
precedence (higher than that of '&') was always evaluating to false
rendering busy loop into a no-op.

Reconcile DDR setup code with corresponding DCD line by line, to avoid
having any doubts if the two are identical (there wer some minor
differences).

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.

Add OpenOCD scipts and notes on usage for various ZII VF610 based
boards.
