i40e: Refactor I40E_MDIO_CLAUSE* macros

The macros I40E_MDIO_CLAUSE22* and I40E_MDIO_CLAUSE45* are using I40E_MASK
together with the same values I40E_GLGEN_MSCA_STCODE_SHIFT and
I40E_GLGEN_MSCA_OPCODE_SHIFT to define masks.
Introduce I40E_GLGEN_MSCA_OPCODE_MASK and I40E_GLGEN_MSCA_STCODE_MASK
for both shifts in i40e_register.h and use them to refactor the macros
mentioned above.
