[PATCH 18/89] clk: bcm: rpi: Rename is_prepared function

[Stephen Boyd]

Quoting Maxime Ripard (2020-02-24 01:06:20)
> The raspberrypi_fw_pll_is_on function doesn't only apply to PLL
> registered in the driver, but any clock exposed by the firmware.
> 
> Since we also implement the is_prepared hook, make the function
> consistent with the other function names, and drop the fw from the
> function name.
