In commit 75918afa649b ("powerpc: Drop old non-generic-board code") we
lost the call to init_85xx_watchdog() which had the effect of disabling
support for the watchdog on 85xx and similar SoCs (i.e. the QorIQ P
Series and T Series).

Admittedly this is a bit ugly but it's the most literal reinstatement of
the code that was lost. At the very least I should probably rename
init_85xx_watchdog() to hw_watchdog_init() so it fits with the rest of
the code.
The other question is how has this gone unnoticed for ~5 years. I think
the answer is because only the keymile boards were using it.
Finally I am wondering if this should be converted to a DM driver. But
given the fact that the watchdog is part of the core and not a
peripheral on the SoC I don't know how that would look (e.g. what would
I put in the DTS?).
So I thought I'd run this up the flag pole as-is and see what feedback I
get.
