For the RK3368, we can reuse the SPI driver (although we'll have to eventually investigate whether it can be merged with the designware_spi.c driver) also used for the RK3288 and RK3399. This adds the necessary compatible string to support the RK3368.
Note that the assumption that GPLL will be clocked at 594MHz is not true for the RK3368, but this will not lead to incorrect functioning (just to a lower-than-expected SPI operating frequency): this has been documented in the driver, so it doesn't cause any headaches when someone next needs to touch the clock code of this driver.
