On devices which have selectable shared memory parts, some beacon may be located in the high part of the shared memory. Instead of extending the already complicated macro, add a new helper function and use that to get the base address of a given beacon. Te helper function will be extended in a subsequent patch to handle different chipsets' requirements, the actual patch contains no functional changes.
