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.

SPI operations have been initially described through macros implicitly
implying the use of a single SPI SDR bus. Macros for supporting dual and
quad I/O transfers have been added on top, generally inspired by vendor
naming, followed by DTR operations. Soon we might see octal
and even octal DTR operations as well (including the opcode byte).
Let's clarify what the macro really means by describing the expected bus
topology in the (quad) program load macro name.
While at modifying it, better add the missing_ OP suffix to align with
all the other macros of the same kind.

So far, the SPINAND_PAGE_READ_FROM_CACHE_OP macro was taking a first
argument, "fast", which was inducing the possibility to support higher
bus frequencies than with the normal (slower) read from cache
alternative. In practice, without frequency change on the bus, this was
likely without effect, besides perhaps allowing another variant of the
same command, that could run at the default highest speed. If we want to
support this fully, we need to add a frequency parameter to the slowest
command. But before we do that, let's drop the "fast" boolean from the
macro and duplicate it, this will further help supporting having
different frequencies allowed for each variant.
The change is also of course propagated to all users. It has the nice
effect to have all macros aligned on the same pattern.
