fbdev: Implement simple blanking in pseudocolor modes for vt8500lcdfb
Implement simple blanking in pseudocolor modes for vt8500lcdfb This follows the style of some other in-tree drivers by just setting the hardware palette colors to all black. True Color modes are not affected, but this at least allows to run xf86-video-fbdev without errors due to blanking being unimplemented.
