matroxfb: restore the registers M_ACCESS and M_PITCH
commit a772d4736641ec1b421ad965e13457c17379fc86 upstream.
When X11 is running and the user switches back to console, the card
modifies the content of registers M_MACCESS and M_PITCH in periodic
intervals.
This patch fixes it by restoring the content of these registers before
issuing any accelerator command.
