[Zhiguang Liu]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1687

Signed-off-by: Zhiguang Liu <zhiguang.liu@intel.com>

IN V3: change the title

IN V2: change the indentation

Two GOP screens will be created if PcdEmuGop is set in
EmulatorPkg.dsc:

gEmulatorPkgTokenSpaceGuid.PcdEmuGop|L"GOP Window 1!GOP Window 2"

I prefer if this ^^ text goes at the start of the commit message, just
after the subject line. I think this information is more important to
be placed near the top since if it important when browsing the repo
log.

I guess this wiki page has added the REF near the top:

https://github.com/tianocore/tianocore.github.io/wiki/Commit-Message-Format

Personally, I think Ref should be added near the end, by the
Signed-off-by, Cc, Reviewed-by tags, but at least the wiki order is
closer. (I think the Ref, Signed-off-by, etc are part of 'tags' block
that should all go at the end of the commit message.)
