fiptool: Enable Visual Studio build
Updates are required to enable the fiptool utility to be built on a
Windows platform. This change modifies the source files to enable
building with Visual Studio (detected via preprocessor settings).
The primary changes are:
1. Provide an implementation of the getopt_long function. This does
not exist in the Visual Studio CRT libraries because Windows
commands normally use '/' not '-' as an option indicator.
2. Redirect some function names to match those supported by the
Visual Studio libraries (when building with Visual Studio).
2. Modify a structure name (stat) to match that provided
by the Visual Studio libraries (_stat).
Note - this change does not provide makefile updates. It only modifies
the sources to enable the fiptool to be built from a Visual
Studio project. In normal use the presence of FIPTOOL.EXE is
enough to satisfy the make requirements. A makefile change may
be derived from the Visual Studio command line information at
some point in the future.

GIC: Allow specifying interrupt properties
The GIC driver initialization currently allows an array of interrupts to
be configured as secure. Future use cases would require more interrupt
configuration other than just security, such as priority.
This patch introduces a new interrupt property array as part of both
GICv2 and GICv3 driver data. The platform can populate the array with
interrupt numbers and respective properties. The corresponding driver
initialization iterates through the array, and applies interrupt
configuration as required.
This capability, and the current way of supplying array (or arrays, in
case of GICv3) of secure interrupts, are however mutually exclusive.
Henceforth, the platform should supply either:
- A list of interrupts to be mapped as secure (the current way).
Platforms that do this will continue working as they were. With this
patch, this scheme is deprecated.
- A list of interrupt properties (properties include interrupt group).
Individual interrupt properties are specified via. descriptors of
type 'interrupt_prop_desc_t', which can be populated with the macro
INTR_PROP_DESC().
A run time assert checks that the platform doesn't specify both.
Henceforth the old scheme of providing list of secure interrupts is
deprecated. When built with ERROR_DEPRECATED=1, GIC drivers will require
that the interrupt properties are supplied instead of an array of secure
interrupts.
Add a section to firmware design about configuring secure interrupts.

ARM platforms: Migrate to using interrupt properties
An earlier patch added provision for the platform to provide secure
interrupt properties. ARM platforms already has a list of interrupts
that fall into different secure groups.
This patch defines macros that enumerate interrupt properties in the
same fashion, and points the driver driver data to a list of interrupt
properties rather than list of secure interrupts on ARM platforms. The
deprecated interrupt list definitions are however retained to support
legacy builds.
Configuration applied to individual interrupts remain unchanged, so no
runtime behaviour change expected.
NOTE: Platforms that use the arm/common function
plat_arm_gic_driver_init() must replace their PLAT_ARM_G1S_IRQS and
PLAT_ARM_G0_IRQS macro definitions with PLAT_ARM_G1S_IRQ_PROPS and

Fix use of MSR (immediate)
The macro DEFINE_SYSREG_WRITE_CONST_FUNC defines an inline function
to an assembly statement that uses the MSR (immediate) instruction
to access the PSTATE. The "i" (immediate) assembly constraint on
the operand was only satisfied when compiling with optimizations
enabled which resulted in the function being optimized out - the
"const uint64_t v" parameter was optimized out and replaced by a
literal value.
When compiling without optimizations, the function call remained and
therefore the parameter is not optimized out - compilation fails as
the constraint is impossible to satisfy by the compiler.
This patch replaces the function encapsulating the use of
the MSR (immediate) with a macro that allows the literal value to be
directly fed to the inline assembly statement
