Correctly dimension the PSCI aff_map_node array
The array of affinity nodes is currently allocated for 32 entries
with the PSCI_NUM_AFFS value defined in psci.h. This is not enough
for large systems, and will substantially over allocate the array
for small systems.
This patch introduces an optional platform definition
PLATFORM_NUM_AFFS to platform_def.h. If defined this value is
used for PSCI_NUM_AFFS, otherwise a value of two times the number
of CPU cores is used.
The FVP port defines PLATFORM_NUM_AFFS to be 10 which saves
nearly 1.5KB of memory.
Fixes ARM-software/tf-issues#192
