viafb: fix ioremap_nocache error handling
Correct the returned error code for remapping the video framebuffer.
Introduce error handling for remapping MMIO register address space to
avoid a NULL pointer dereference. Disable hardware acceleration if
remapping MMIO register address space failed as those registers are only
used for hardware acceleration.
