spd: trusty: allow clients to retrieve service UUID

This patch implements support for the 64-bit and 32-bit versions of
0xBF00FF01 SMC function ID, as documented by the SMCCC, to allow
non-secure world clients to query SPD's UUID.

In order to service this FID, the Trusty SPD now increases the range
of SMCs that it services. To restrict Trusty from receiving the extra
SMC FIDs, this patch drops any unsupported FID.

Verified with TFTF tests for UID query and internal gtest for Trusty.

Main Fixes:

Use int32_t replace int [Rule 4.6]

Added explicit casts (e.g. 0U) to integers in order for them to be
compatible with whatever operation they're used in [Rule 10.1]

Force operands of an operator to the same type category [Rule 10.4]

Fixed if statement conditional to be essentially boolean [Rule 14.4]

Voided non c-library functions whose return types are not used
[Rule 17.7]

Standardise header guards across codebase

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

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.

spd: trusty: add SET_ROT_PARAMS handling

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.

Resolve build errors flagged by GCC 6.2

With GCC 6.2 compiler, more C undefined behaviour is being flagged as
warnings, which result in build errors in ARM TF build.

The specific issue that this patch resolves is the use of (1 << 31),
which is predominantly used in case statements, where 1 is represented
as a signed int. When shifted to msb the behaviour is undefined.

The resolution is to specify 1 as an unsigned int using a convenience
macro ULL(). A duplicate macro MAKE_ULL() is replaced.

Fixes ARM-software/tf-issues#438
