soc/mediatek/mt8196: Enable lastbus debug hardware
Lastbus is a bus debug tool. When the bus hangs, the bus transmission
information before resetting will be recorded.
The watchdog cannot clear it and it will be printed out on the serial
console for bus hanging analysis.
TEST=build pass, and check log with:
