In order to save power when AP side is suspend,
the DBLOG need to be put into low power mode.
GIC need to be power off to save power. before GIC

after resume, we need to restore the gic setting.
irqsteer need to be used to wakeup the AP side

`ERRATA_A72_859971``: This applies errata 859971 workaround to Cortex-A72
CPU. This needs to be enabled only for revision <= r0p3 of the CPU.
859971: Speculative instruction prefetch to Execute-never (XN) memory
could cause deadlock or data integrity issue
On i.MX8QM, we are using r0p2, so enable this errata.

then this cluster's power and CCI port can be also turned off
to save power.
Also add cluster and CCI low power mode request to SCFW.
