This patch exposes clk_gate_ops::is_enabled as functions
that can be directly called and assigned in places like this so
we don't need wrapper functions that do nothing besides forward
the call.

Here the prefix does not reflect the type of its argument, it might be
acceptable for a veiled function, but it is not wanted for the exported
function. Something like clk_hw_gate_is_enabled() is expected here, but
again, let's firstly come to an agreement, that the export is needed.
