x86: dts: Remove coreboot_fb.dtsi

There is no need to keep a separate coreboot_fb.dtsi since now we
have a generic coreboot payload dts.

While we are here, this also remove the out-of-date description in
the documentation regarding to coreboot framebuffer driver with
U-Boot loaded as a payload from coreboot. As the testing result with
QEMU 2.5.0 shows, the driver just works like a charm.

- Set framebuffer graphics resolution (1280x1024 32k-color (1:5:5))
- Keep VESA framebuffer
And include coreboot_fb.dtsi in your board's device tree source file, like:
/include/ "coreboot_fb.dtsi"
At present it seems that for Minnowboard Max, coreboot does not pass through
the video information correctly (it always says the resolution is 0x0). This
works correctly for link though.
Note: coreboot framebuffer driver does not work on QEMU. The reason is unknown
at this point. Patches are welcome if you figure out anything wrong.
Test with QEMU for bare mode
----------------------------
QEMU is a fancy emulator that can enable us to test U-Boot without access to
