gk20a_pllg_disable() is only used in the context of gk20a_clk_fini().
Move its body there and rename _gk20a_pllg_enable() and
_gk20a_pllg_disable() to non-underscored versions.

This class supports a WFI method (0x0078) that's not present on the
KeplerChannelGpfifoA class.
The binary driver exposes both classes on these GPUs for some reason,
though there doesn't appear to be any difference in the setup that's
done for each (ie. even if you allocate GpfifoA, the WFI method will
still work).
We shall just expose GpfifoB, as I don't see a good reason to report
the presence of both.
