Subject: [PATCH v2 2/2] clk: rockchip: remove unused rockchip_clk_protect_critical function

From: Andi Shyti <andi@...zian.org>

because there is no need anymore to enable critical clocks in
each driver, this function is not necessary anymore.

The drivers having critical clocks use the CLK_IS_CRITICAL flag.
