Michael Hennerich 97174b1e6a spi: cadence: cache reference clock rate during probe 
commit 4d163ad79b155c71bf30366dc38f8d2502f78844 upstream.

The issue is that using SPI from a callback under the CCF lock will
deadlock, since this code uses clk_get_rate().

Fixes: c474b38665463 ("spi: Add driver for Cadence SPI controller")
