[PATCH 1/2] mailbox: stm32-ipcc: add COMPILE_TEST dependency

[Martin Kaiser]

This allows compiling the driver on architectures where the hardware is not
available. Most other mailbox drivers support this as well.

I used this for testing the trivial patch that removes the duplicate error
message. Also, compiling the driver on x86_64 worked without errors.
