ARM: armv7: move ARMV7_PSCI_NR_CPUS to Kconfig 

Move this option to Kconfig and set its default value to 4; this
increases the number of supported CPUs for some boards.

It consumes 1KB memory per CPU for PSCI stack, but it should not
be a big deal, given the amount of memory used for the modern OSes.

The maximum number of CPUs supported in the PSCI firmware.
It is no problem to set a larger value than the number of
CPUs in the actual hardware implementation.
