[PATCH 0/2] mailbox: bcm: Unregister controllers before destroying DMA pools

[Guangshuo Li]

Explicitly unregister the Broadcom FlexRM and PDC mailbox controllers
before destroying their DMA pools, so channel shutdown can still
release its ring allocations.

Prepared with AI assistance and reviewed by the submitter. The affected
objects were build-tested with W=1; configuration details are included
with each patch. No hardware or fault-injection tests were performed.
