binaryPI: Fix UMA calculations
Vendorcode decides already in AMD_INIT_POST the exact location
of UMA memory. To meet alignment requirements, it will extend
uma_memory_size. We cannot calculate base from size and TOP_MEM1,
but need to calculate size from base and TOP_MEM1 instead.
Also allows selection of UmaMode==UMA_SPECIFIED to manually set
amount of memory reserved for framebuffer.
