net: stmmac: rk: add GMAC_CLK_xx constants, simplify RGMII definitions

Browse source

All the definitions of the RGMII related xxx_GMAC_CLK_xxx definitions
use the same field values to select the clock rate. Provide common
definitions for these field values, passing them in to a single macro
for each variant that generates the appropriate values for the speed
register.

No change to produced code on aarch64.
