This mini-series allows to allocate frame buffer memory in desired
location. Allocation of a frame buffer memory in a special memory region
allows bypassing of so-called IO Coherency aperture which is typically set
as a range 0x8z-0xAz.
I.e. all data traffic to PGU bypasses IO Coherency block
and saves its bandwidth for other peripherals.
