watchdog: watchdog_dev: Use device tree alias for naming watchdogs
Currently there is no way to easily differentiate multiple
watchdog devices. The watchdogs are named by the order they
are probed.
1st probed watchdog: /dev/watchdog0
2nd probed watchdog: /dev/watchdog1
...
This change uses the alias of the watchdog device node for
the name of the watchdog.
aliases {
watchdog0 = "/...../...."
watchdog3 = "/..../....."
watchdog2 = "/..../....."
...
}
This will translate to...
/dev/watchdog0
/dev/watchdog3
/dev/watchdog2
v2
Assign alias number to id in watchdog_core instead of watchdog_dev.
If failed to get id, fallback to original ida_simple_get call.
