Exynos850 has the same version of USI SPI (v2.1) as GS101. Drop the fifo_lvl_mask and rx_lvl_offset and switch to the new port config data. Backward compatibility with DT is not broken because when alises are set: - the SPI core will set the bus number according to the alias ID - the FIFO depth is always the same size for exynos850 (64 bytes) no matter the alias ID number. Advantages of the change: - drop dependency on the OF alias ID. - FIFO depth is inferred from the compatible. Exynos850 integrates 3 SPI IPs, all with 64 bytes FIFO depths. - use full mask for SPI_STATUS.{RX, TX}_FIFO_LVL fields. Using partial masks is misleading and can hide problems of the driver logic. Just compiled tested.
