Maybe you can use devm_clk_get here too.

That requires all users of the driver to be using CONFIG_CLKDEV, which
I *think* is safe to do, but better check: Russell, do you know if
it's safe to use
this feature from clkdev in the PL011 driver?

It seems so to me and most likely works on the systems I have (Ux500, U300,
Nomadik, Integrator, RealView) but the world of PL011 is so big...
