[PATCH v6 2/3] clk: gate: expose clk_gate_ops::is_enabled

[gabriel.fernandez at st.com]

From: Gabriel Fernandez <gabriel.fernandez at st.com>

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.
