mfd: arizona: Split of_match table into I2C and SPI versions
The Arizona driver has both some devices which only have an I2C interface and some which only have a SPI interface. Currently both of these share an of_match table, but this means inapproriate compatibles are available for each interface. Tidy this up by creating a table for each interface listing only the appropriate compatibles.
