[PATCH] efi: gop: use screen_base directly instead of shadow buffer

[Ahmad Fatoum <a.fatoum@barebox.org>]

The EFI GOP protocol operates on the hardware framebuffer and calls
fb_damage() to notify the driver of updates. Using fb_get_screen_base()
would return the shadow buffer when enabled, causing GOP writes to go
into the shadow instead of the actual framebuffer.

Do as the simplefb fixup does and use the screen_base.
