net: sun8i_emac: Use consistent clock bitfield definitions 

While the R40 uses a different register for EMAC clock configuration
than other chips, the register has a very similar layout. Reuse the
existing bitfield definitions in this file, since they match.

This allows the driver to compile on the H6 platform, where the
CCM_GMAC_CTRL definitions are not present.
