When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.
