[PATCH] ARM: psci: fix warning on psci_init if ARM_PSCI is undefined

[Christian Engelmayer]

Commit e71246a (PSCI: Add initial support for PSCIv0.2 functions) changed the
return type of function psci_init() from void to int, but left the static
inline stub used if CONFIG_ARM_PSCI is not defined otherwise untouched. This
results in minor compile warning "warning: no return statement in function
returning non-void [-Wreturn-type]". The return value is currently not
evaluated by the only caller anyway.
