2bec46dc97 vga optimization (Glauber Costa) 
Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.

In this patch, we map the linear frame buffer as RAM,
make sure it has dirty region tracking enabled, and then
just let the region to be written.

4efe27556d better type checking for vga (Glauber Costa) 
unsigned long is too bad of a type. Use ram_addr_t instead.
