core: arm: psci: add suspend resume common functions
Add cpu suspend/resume common functions.
Platform psci suspend functions need to call
sm_pm_cpu_suspend(arg, platform_suspend) to runs into suspend.
The i.MX flow is:
psci_cpu_suspend->imx7_cpu_suspend->sm_pm_cpu_suspend(arg, func)
The "func" runs in on-chip ram that not losing power when
system runs into suspend or low power state. Argument "arg" is
passed to function "func" as argument through register "r0".

Add __weak property for the PSCI functions, developers could

PSCI is handled in monitor mode, and when finished, directly returns
to nsec world.
