net: mdio: realtek-rtl9300: use command runner for read_c22()

Convert the final missing read_c22() path to the new read enabled command
runner. Do it the same way as other implementations.

- bus calls otto_emdio_read_c22()
- this hands over to SoC specific otto_emdio_9300_read_c22()
- finally the registers are filled and the runner issued

With this cleanup remove the obsolete helper otto_emdio_wait_ready()
