Currently clk driver enables it on all SoCs, but FUSE may require a higher core voltage on Tegra30 while enabled. Move the quirk into the FUSE driver and make it specific to Tegra124.

Now FUSE device must be resumed using runtime PM API in order to initialize the FUSE power state. Add runtime PM support to the FUSE driver.

It's unlikely to happen in practice, nevertheless let's correct it for completeness.
