[PATCH] ARM: make unexported functions static

[ben.dooks@codethink.co.uk (Ben Dooks)]

There are three functions that do not get exported from the
psci_smp.c file that if we make static then the following
warnings get squashed:

arch/arm/kernel/psci_smp.c:61:5: warning: symbol 'psci_cpu_disable' was not declared. Should it be static?
arch/arm/kernel/psci_smp.c:74:6: warning: symbol 'psci_cpu_die' was not declared. Should it be static?
arch/arm/kernel/psci_smp.c:86:5: warning: symbol 'psci_cpu_kill' was not declared. Should it be static?
