Hi,

Clean up the stmmac MDIO code:
- provide an address register formatter to avoid repeated code
- provide a common function to wait for the busy bit to clear
- pre-compute the CR field (mdio clock divider)
- move address formatter into read/write functions
- combine the read/write functions into a common accessor function
- move runtime PM handling into common accessor function
- rename register constants to better reflect manufacturer names
- move stmmac_clk_csr_set() into stmmac_mdio
- make stmmac_clk_csr_set() return the CR field value and remove
  priv->clk_csr
- clean up if() range tests in stmmac_clk_csr_set()
- use STMMAC_CSR_xxx definitions in initialisers

Untested on hardware; would be grateful for any testing people can do.

v2: add "Return:" to patch 1 and 9
