f5f599daa0 drm/bochs: fix blanking 
[ Upstream commit e740ceb53e4579a7a4063712cebecac3c343b189 ]

VGA_IS1_RC is the color mode register (VGA_IS1_RM the one for monochrome
mode, note C vs. M at the end).  So when using VGA_IS1_RC make sure the
vga device is actually in color mode and set the corresponding bit in the
misc register.

Reproducible when booting VMs in UEFI mode with some edk2 versions (edk2
fix is on the way too).  Doesn't happen in BIOS mode because in that
case the vgabios already flips the bit.

796c3e35ac drm/bochs: Move to tiny/ 
The bochs driver is only ~600 lines of code. Putting it into tiny/
cleans up the DRM directory slightly. Some style problems were fixed
and unneeded include statements were removed. No functional changes.

v2:
	* make bochs_mode_funcs static (Daniel, kernel test robot)
	* rebase onto aperture API changes
