Add early console support for generic linear framebuffer devices.
This driver supports probing from cmdline early parameters
or from the device-tree using information in simple-framebuffer node.
The EFI functionality should be retained in whole.
The driver was disabled on ARM because of a bug in early_ioremap
implementation on ARM.

It looks like this is not actually related to fbdev, and since drivers are
moving from fbdev/simplefb towards drm/simpledrm, maybe it would be
better to put this into either drivers/gpu/drm/tiny/ or possibly
drivers/video/console to let this be used without enabling fbdev?
