Subject: [PATCH] soc/mediatek/mt8188: Add tracker dump

Tracker is a debugging tool. When bus timeout occurs, the system will
reboot and latch some values of tracker registers which could be used
for debugging.

This function will be triggered only when it encounters the bus
hanging issue.

TEST=build pass
BUG=b:236331724
