cma: Add API to get the start address of a CMA region

When setting CMA up at a fixed region, it is possible for the address
to be shared between multiple subsystems. If the address is placed
dynamically, there is no mechanism to be able to get the start address
of the region. Drivers may wish to do keep track of allocations relative
to the start address so add an API to get the start region of a CMA
address.
