arm64: kernel: rename __cpu_suspend to keep it aligned with arm
commit af391b15f7b56ce19f52862d36595637dd42b575 upstream.
This patch renames __cpu_suspend to cpu_suspend so that it's aligned
with ARM32. It also removes the redundant wrapper created.
This is in preparation to implement generic PSCI system suspend using
the cpu_{suspend,resume} which now has the same interface on both ARM
and ARM64.
