Miquel Raynal d81ad9d78e mtd: spinand: Add a frequency field to all READ_FROM_CACHE variants
These macros had initially no frequency field. When I added the "maximum
operation frequency" field, I did it initially on very common macros and
I decided to add an optional field for that (with VA_ARGS) in order to
prevent massively unreadable changes. I then added new variants in the
spinand.h header, and requested a frequency field for them by
default. Some times later, I also added maximum frequencies to other
existing variants, but I did it incorrectly, without noticing I was
wrong because the field was optional.

This mix is error prone, so let's do what I should have done since the
very beginning: add a frequency field to all READ_FROM_CACHE variants.

There is no functional change.
