just a "everything that worked before still works" :-)

Using orphaned clocks should already produce strange issues most of the time -
for example I see clk_disable mismatches when suspending a rk3288 board,
before this patchset.

But nevertheless we now disallow the usage of orphaned clocks completely while
before it was possible to knowingly/unknowingly use them.

And while hopefully most drivers should handle an EPROBE_DEFER from clk_get
just fine, there may still be one or two lurking around that would need fixing
then ;-)
