MLK-12088 ARM: imx: low power idle support for imx7d single core

When only single core online for i.MX7D, the secondary core wfi
flag should be set to make sure low power idle can be entered when
last core enters wfi. Otherwise, DDR/CCM/ANATOP will NOT enter
low power mode as the secondary core wfi flag is always clear;

Make sure the last power up slot do the ack for single core case.
