[U-Boot] [PATCH v2 00/14] x86: Bring qemu-x86_64 target in travis-ci build/testing

[Bin Meng]

At present the QEMU x86_64 target is broken here and there, for
example with newer compiler it even does not boot. EFI loader does
not work either.

This series is a combination of Heinrich's EFI loader fixes and
my fixes to QEMU x86_64 target. To enable qemu-x86_64 target in
travis-ci for build and testing, uboot-test-hooks needs to be
updated and the PR is sent.

The series is available at u-boot-x86/qemu-working for testing.

Changes in v2:
- some rewording in the doc per Heinrich's review comments
- Change to use MHz instead of Hz for the early timer frequency
- Change the config option value to 400 which indicates 400 MHz
- new patch to generate grub_x64.efi for qemu-x86_64 for travis-ci
- new patch to update to use QEMU 3.0.0 for travis-ci testing
