[PATCH] Use phys_to_virt instead of bus_to_virt in vesafb

Several people (including Alan Cox) on lkml claimed that the BIOS
returns CPU addresses, so using phys_to_virt is actually correct -
and it makes my kernel compile again.

As vesafb only compiles on i386, using a more portable API isn't useful,
anyway.
