  From: Simon Glass <simon.glass@canonical.com>

The mcheck registry tracks concurrent allocations for pedantic checking.
The current size of 6608 entries is insufficient when running the full
pytest suite, causing registry overflow warnings.

Increase REGISTRY_SZ to 12000 to handle the full test suite.
