rk_spi: Do not change the clock with the driver lock heldHEADmain

The clock framework can sleep, it takes the clock topology sx lock.  Calling
clk_set_freq() and clk_get_freq() from rk_spi_hw_setup() with the driver
mutex held triggers a witness warning about a sleepable lock acquired after
a non-sleepable one, on the first transfer that raises the clock.

Set the clock in a new function that is called before taking the lock, and
only keep the register setup under the lock.
