core: change return type for tee_entry_std() TEE_Result

Changes the return type for the function tee_entry_std() to TEE_Result
in order to make it independent of optee_smc.h. tee_entry_std() is also
called from yielding_call_with_arg() and it doesn't make sense for that
function to return values based on the SMC ABI.

With this we're doing an ABI change for FF-A, but that should not make a
difference for the driver since that only test for 0 or !0. In addition
if !0 is returned the communication has broken down completely so there
not much left to recover from. Note that this patch does not require
changes in the Linux kernel driver.

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.
