[WATCHDOG] mpc83xx_wdt: add support for MPC86xx CPUs
On MPC86xx the watchdog could be enabled only at power-on-reset, and could
not be disabled afterwards. We must ping the watchdog from the kernel
until the userspace handles it.
MPC83xx CPUs are only differ in a way that watchdog could be disabled
once, but after it was enabled via software it becomes just the same as
MPC86xx.
Thus, to support MPC86xx I added the kernel timer which pings the watchdog
until the userspace opens it.
Since we implemented the timer, now we're able to implement proper
handling for the CONFIG_WATCHDOG_NOWAYOUT case, for MPC83xx and MPC86xx.
Also move the probe code into subsys_initcall, because we want start
pinging the watchdog ASAP, and misc devices are available in
subsys_initcall.
