allwinner: Separate code to power off self and other CPUs
Currently, sunxi_cpu_off() has two separate code paths: one for the
local CPU, and one for other CPUs. Let's split them in to two functions.
This actually simplifies things, because all callers either operate on
the local CPU only (sunxi_pwr_down_wfi()) or other CPUs only
(sunxi_cpu_power_off_others()). This avoids needing a second MPIDR read
to choose the appropriate code path.
