soc/mediatek/mt8188: 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 for bus hanging
analysis.

There are two versions for lastbus:
Version 1 for MT8186, and version 2 for MT8188.

BUG=b:263753374
TEST=build pass.
