[PATCH] fbdev/fsl-diu-fb: Fix srapse warning due to virt_to_phys() prototype change

[Stanislav Kinsburskii]

Explicitly cast __iomem pointer to const void* with __force to fix the
following warning:

   incorrect type in argument 1 (different address spaces)
      expected void const volatile *address
      got char [noderef] __iomem *screen_base
