Graeme Gregory a86865ac42 PSCI: fix limit of 256 CPUs caused by cast to unsigned char ...

In psci_setup.c psci_init_pwr_domain_node() takes an unsigned
char as node_idx which limits it to initialising only the first
256 CPUs. As the calling function does not check for a limit of
256 I think this is a bug so change the unsigned char to
uint16_t and change the cast from the calling site in
populate_power_domain_tree().

Also update the non_cpu_pwr_domain_node structure lock_index
to uint16_t and update the function signature for psci_lock_init()
appropriately.

Finally add a define PSCI_MAX_CPUS_INDEX to psci_private.h and add
a CASSERT to psci_setup.c to make sure PLATFORM_CORE_COUNT cannot
exceed the index value.
