Kernel/aarch64: Remove specific aarch64 code in BootFramebufferConsole

Browse source 
The MemoryManager now works, so we can use the same code as on x86 to
map the framebuffer. Since it uses the MemoryManager, the initialization
of the BootFramebufferConsole has to happen after the MemoryManager is
working.
