psci system_reset and system_off calls now retrieve shutdown scope on
the fly. The default scope is system, but it can be changed by calling
pm_system_shutdown(2, scope)

Until full support for different restart scopes becomes available with
PSCI 1.1 this change allows users to set the reboot scope to match
their application needs.

Possible scope values:
0 - APU subsystem: does not affect RPU, PMU or PL
1 - PS only: shutdown/restart entire PS without affecting PL
2 - System: shutdown/restart applies to entire system

Implement ioctl APIs which uses MMIO operations
to control RPU operations. Below IOCTLs are supported
in this patch:
  * Get RPU operation mode
  * Set RPU operation mode
  * Configure RPU boot address (OCM/TCM)
  * Configure TCM combined mode

During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.

Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.

The state argument of the pm_self_suspend API encodes the state to
which the APU intends to suspend. The state can be:
- PM_APU_STATE_CPU_IDLE - processor power down, all memories remain
  on
- PM_APU_STATE_SUSPEND_TO_RAM - all processors powered down, L2$
  powered down, all OCM banks in retention and DDR in
  self-refresh.
The calls for setting requirements for L2$ and OCM banks are now
redundant and removed.
