Subject: [PATCH v7 2/3] clk: gate: expose clk_gate_ops::is_enabled

From: Gabriel Fernandez <gabriel.fernandez@...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.
