When Linux runs in normal world, it expects the PL310 to be initially
disabled, and then invokes SMCs to enable it.
Let CFG_PL310_SIP_PROTOCOL=y, and the L2 cache will be left untouched
until the OS enables it.

plat-sam: add SCMI server foundation
Add foundations for SCMI server support. This will be used to expose
clocks and regulators to non-secure world.

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.
