[PATCH v6 2/8] ati-vga: Also switch mode on HW cursor enable bit change

[BALATON Zoltan <balaton@eik.bme.hu>]

This does nothing for most drivers but works around issue and fixes
output with the Solaris R128 driver that only sets display parameters
after enabling CRT controller which we would miss otherwise.
