spi: cavium: Follow renaming of SPI "master" to "controller" 
In commit 8caab75fd2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
this driver.
