The CONFIG_MIPS_CPS SMP implementation should be able to handle all
cases the CONFIG_MIPS_CMP implementation does, but without requiring
bootloader assistance. It is also required in order to make use of
features such as hotplug & cpuidle core power gating. Enable it by
default for Malta configs that previously enabled the now deprecated
CONFIG_MIPS_CMP, and disable the latter. The local version suffix "cmp"
is removed rather than replaced with "cps" since there are other ways to
tell that the CPS SMP implementation is in use (the "VPE topology" line
in the boot log being one).

These defconfigs contain the CONFIG_M25P80 symbol, which is now
dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to satisfy
the new dependency.
At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

Nobody is maintaining SMTC anymore and there also seems to be no userbase.
Which is a pity - the SMTC technology primarily developed by Kevin D.
Kissell <kevink@paralogos.com> is an ingenious demonstration for the MT
ASE's power and elegance.
Based on Markos Chandras <Markos.Chandras@imgtec.com> patch
https://patchwork.linux-mips.org/patch/6719/ which while very similar did
no longer apply cleanly when I tried to merge it plus some additional
post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to
merge once upon a time.

The previous NR_CPUS=2 default is not an optimal default for current
Malta setups where it is common to have more than 2 CPUs available. It
makes sense to increase this to a number which covers all common setups
currently in use, such that all of those cores are usable. 8 seems to
fit that description.
If the user has less than 8 CPUs & they wish to have a more optimal
kernel they can simply reduce this in their config. It makes sense for
the default to work on as many systems as possible.
