Make functions static where possible, otherwise add prototypes or make

The code for checking whether a BAR address range is valid will break
out of the loop when a start address of 0x0 is encountered.
This behaviour is wrong since by breaking out of the loop we may miss
the BAR that describes the EFI frame buffer in a later iteration.
Because of this bug I can't use video=efifb: boot parameter to get
efifb on my new ThinkPad E550 for my old linux system hard disk with
3.10 kernel. In 3.10, efifb is the only choice due to DRM/I915 not
supporting the GPU.
This patch also add a trivial optimization to break out after we find
the frame buffer address range without testing later BARs.

The efifb quirks handling based on DMI identification of the platform is
specific to x86, so move it to x86 arch code.

The EFI FB quirks from efifb.c are useful for simple-framebuffer devices
as well. Apply them by default so we can convert efifb.c to use
efi-framebuffer platform devices.
