[PATCH 1/2] net: phy: micrel: use devm_clk_get_optional_enabled for the rmii-ref clock

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@xxxxxxxxx>

While the external clock input will most likely be enabled, it's not
guaranteed and clk_get_rate in some suppliers will even just return
valid results when the clock is running.

So use devm_clk_get_optional_enabled to retrieve and enable the clock
in one go.
