Igal Liberman 2dbba24088 phy: marvell: rename comphy related definitions to COMPHY_XX
Currently, all comphy definitions are PHY_TYPE_XX and PHY_SPEEED_XX.
Those definition might be confused with MDIO PHY definitions.

This patch does the following changes:
 - PHY_TYPE_XX --> COMPHY_TYPE_XX
 - PHY_SPEED_XX --> COMPHY_SPEED_XX

This improves readability, no functional change.
