bus: ti-sysc: Fix watchdog quirk handling
I noticed that when probed with ti-sysc, watchdog can trigger on am3, am4
and dra7 causing a device reset.
Turns out I made several mistakes implementing the watchdog quirk handling:
1. We must do both writes to spr register
2. We must also call the reset quirk on disable
3. On am3 and am4 we need to also set swsup quirk flag
I probably only tested this earlier with watchdog service running when the
watchdog never gets disabled.
