No, the way to do this is to fix x86 to enable the clock API there.  The
x86 maintainers couldn't be bothered when I submitted a patch and
getting anyone to take a patch to make it available by default appears
to be unreasonably hard but perhaps if someone from Intel tries the x86
maintainers might take a patch...

We shouldn't be adding special case code to every driver that might need
a clock that gets used on an Intel system.
