Add support for Cortina CS4315/CS4340 10G PHY.
- This driver loads CS43xx firmware to initialize Cortina PHY.
- To define macro CONFIG_PHY_CORTINA will enable this driver.
- Cortina PHY has non-standard offset of PHY ID registers, so define own get_phy_id().

v4: add support for loading cortina phy ucode from NAND/SPI/SD/REMOTE v3: move devad as '0' in cortina.c instead of in phy.c v2: no change.

Where is "rc" declared?
