f62229227c efi: Support copy framebuffer
Add support for this to EFI in case it becomes useful. At present it just
slows things down. You can enable CONFIG_VIDEO_COPY to turn it on.

Now that Linux has accepted these tags, move the device tree files in
U-Boot over to use them.

1834c081d3 efi: Add video support to the app
The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd
   -drive id=disk,file=try.img,if=none,format=raw -nic none
   -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0

c79cbb5952 x86: dts: Define a default TSC timer frequency
If for some reason, TSC timer frequency cannot be determined from
hardware, nor is it specified in the device tree, U-Boot will panic
resulting in endless reset during boot.

Let's define a default TSC timer frequency using the Kconfig value
CONFIG_X86_TSC_TIMER_FREQ (note: #include must be used instead of
/include/ otherwise the macro is not pre-processed).
