Subject: [PATCH v2 12/91] clk: bcm: rpi: Make sure the clkdev lookup is removed

The clkdev lookup created for the cpufreq device is never removed if
there's an issue later in probe or at module removal time.

Let's convert to the managed variant of the clk_hw_register_clkdev function
to make sure it happens.
