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.

drivers: add reset controller framework

Adds a common reset controller framework rstctrl for interfacing
reset controllers exposed by a platform.

Reset controller consumers can act on relate reset level with
rstctrl_assert(), rstctrl_deassert() and friends.

Reset controller consumers can claim exclusive access to the reset
level woth rstctrl_get_exclusive(), rstctrl_put_exclusive().

Reset controller provider drivers call rstctrl_register_provider()
to allow other drivers to get a reset control reference from
a devicetree reference. Reset controller driver are identified with
type DT_DRIVER_RSTCTRL.

A reset controller provider exposes struct rstctrl instances made of
an opaque private reference (a private data pointer or an unsigned
integer identifier), an reset controller operators reference and
the exclusive claim state.
