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.
