Andreas Kling 7e4bc04057 Kernel: Don't remap BochsGraphicsAdapter MMIO registers on every access 
We were creating a new memory mapping every time WindowServer performed
a buffer flip. This was very visible in whole-system profiles, as the
mapping and unmapping of MMIO registers caused quite a bit of kmalloc()
and kfree() churn.

Avoid this problem by simply keeping the MMIO registers mapped.
