plat-sam: pm: add support for setting suspend mode

PSCI allows entering platform suspend with SYSTEM_SUSPEND call which
is meant to enter the system in its deepest power state. sama5d2
platform supports multiple suspend power states. Currently, Linux
supports the atmel.pm_modes command line option which allows to select
this suspend state. Since Linux uses PSCI SYSTEM_SUSPEND to enter
suspend mode, we are not able to pass information (such as done for
CPU_SUSPEND). In order to select the mode that will be entered by
SYSTEM_SUSPEND from normal world and thus select the desired suspend state,
SMCs are added to allow selecting and getting this power mode.
