spi: amlogic-spifc-a1: Support per spi-mem operation frequency switches
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.
