The TRBE driver support is build as a module, we found some driver issues
based on the patchset [1] and set CONFIG_CORESIGHT_TRBE=m.
1. TRBE driver potential sleep in atomic context when unregister device
2. Multiple free the platform data resource when rmmod coresight TRBE
driver

I am glad that ACPI based device enablement is already helping in getting more
test coverage for the TRBE driver itself. I have just posted a new version for
the above series.
