[10/24] spi: mxic: Support per spi-mem operation frequency switches

Commit Message

Miquel Raynal Oct. 25, 2024, 4:14 p.m. UTC

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.
