Subject: [PATCH 1/8] watchdog: bcm2835: Move the driver to the soc/ directory.

The binding for the bcm2835 "wdt" actually covers a large range of the
PM block's register space.  The WDT is not a separate HW block from
the rest of power domain management, so move the driver to the soc/
directory in preparation for expanding its role to cover power
domains.

This move does result in the driver being made mandatory for the
BCM2835 platform, which is probably actually reasonable given that
it's necessary for reboot/halt support.
