Fix order of #includes

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions in order to retain header groupings,
minimise changes to imported headers, and where there are headers within
the #if and #ifndef statements.

Migrate secure payload dispatchers to new SMC terminology

Since Issue B (November 2016) of the SMC Calling Convention document
standard SMC calls are renamed to yielding SMC calls to help avoid
confusion with the standard service SMC range, which remains unchanged.

http://infocenter.arm.com/help/topic/com.arm.doc.den0028b/ARM_DEN0028B_SMC_Calling_Convention.pd

A previous patch introduced a new define for yielding SMC call type.
This patch updates the secure payload dispatchers (except the TSPD) to
use this new define and also migrates the code to use the new
terminology.

If Trusty is not running on the device, then Verified Boot is
not supported and the NS layer will fail gracefully later during
boot. This patch just returns success for the case when Trusty is
not running on the device and the bootloader issues SET_ROT_PARAMS
call during boot, so that we can at least boot non-Android images.

Check Trusty is present during the SPD's initialization

Add a debug assertion in the initialization function of Trusty's SPD
to check for the presence of Trusty. If Trusty is absent then the SPD's
setup function already detects it and returns an error code so the init
function will never been called. Therefore, a debug assertion is enough
to catch this improbable error case.

Fix compilation warning in Trusty SPD

In release builds, the Trusty SPD fails to build because of an unused
variable. Note that this warning message doesn't show in debug builds
because INFO() messages are not compiled out like in release mode.

This patch fixes this issue by removing this variable and using its
value in place directly in the INFO() macro call.
