[WATCHDOG] mpc83xx_wdt: rename to mpc8xxx_wdt

Rename the driver because now we support some MPC86xx processors.

There are no changes to the mpc83xx_wdt.c file, yet.  When possible, we do
file renames and changes separately (because Linus once asked so, because
it helps git to track the renamed files).

+          For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.
