tests: drivers: memc: Simplify filters

Currently, every boards that implement a memory controller add an entry
in tests/drivers/memc/ram/testcase.yaml. However, the configuration is
exactly the same for all the boards. So, we can just consider that any
board that declare "memc" capability has to be tested.

For the record here are the boards that has the memc capability:
