Instead of accessing the function to set the watchdog timer directly,
register a platform driver the platform could register to use this
watchdog driver.

Convert the bcm47xx_wdt.c driver to the new watchdog core api.

The nowayout parameter is now added unconditionally to the module.

nowayout is actually a boolean value.
So make it bool for all watchdog device drivers.

Use the current logging styles.

Make sure all output has a prefix.
Add missing newlines.
Remove now unnecessary PFX, NAME, and miscellaneous other #defines.

This patch add support for the bcma bus. Broadcom uses only Mips 74K
CPUs on the new SoC and on the old ons using ssb bus there are no Mips
74K CPUs.

Prepare bcm47xx to support different System buses. Before adding
support for bcma it should be possible to build bcm47xx without the
need of ssb. With this patch bcm47xx does not directly contain a
ssb_bus, but a union contain all the supported system buses. As a SoC
just uses one system bus a union is a good choice.

This add watchdog driver for broadcom 47xx device.
It uses the ssb subsytem to access embeded watchdog device.

Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.

Note : A patch for exporting the ssb_watchdog_timer_set will
be submitted on next linux-mips merge. Without this patch it can't 
be build as a module.
