soc/mediatek/mt8186: add tracker dump
Tracker is a debugging tool, and MT8186 only supports AP tracker.
When bus timeout occurs, the system reboots and latches some values
which could be used for debugging.
This function will be triggered only when it encounters the bug
hanging issue.
BUG=b:202871018
TEST=range of registers are dumped as expected.
