Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the arm926ejs timers implementation.
The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.
This patch is similiar to the patch Dirk Behme posted
for the armv7/omap-common/timer.c and added suggestions
from Reinhard Meyer.
Tested on the arm926ejs mx27 based magnesium board

* add's a warning to all files, which need update to new SoC access

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.
The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).

AT91CAP9 and AT91SAM9 SoCs are very close hardware wise, so a
common infrastructure can be used. Let this infrastructure be
named after the AT91SAM9 family, and move the existing AT91CAP9
files to the new place.

The timer on AT91CAP9/AT91SAM9 is supplied by the SoC, and not by
the board, so use timer_init() instead of interrupt_init().
