Every ->exec_op() call correctly configures the spi bus speed to the
maximum allowed frequency for the memory using the constant spi default
parameter. Since we can now have per-operation constraints, let's use
the value that comes from the spi-mem operation structure instead. In
case there is no specific limitation for this operation, the default spi
device value will be given anyway.
The per-operation frequency capability is thus advertised to the spi-mem
core.

This patch sets the clock rate (spi_transfer->max_speed_hz) from the
amlogic_spifc_a1_exec_op().

This enhancement eliminates the need for a loop in the
amlogic_spifc_a1_exec_op() function and allows the SPI core to
dynamically divide transactions into appropriately sized chunks.
