The Allwinner code defined a platform specific GIC setup. However
we don't need secure IRQs or a special setup, so we can easily go with
the default ARM GIC setup provided by the driver.
Remove the unneeded code file, associated calls and code lines.

The generic ARM GIC setup code has an assertion about a valid GICv3
redistributor base address.
Remove this to allow to setup GICv2s using the generic interface.

Currently the generic GIC driver code has an assert to halt if no valid
pointer to the list of secure interrupts is specified.
Rework this to barf only if the number of secure interrupts is greater
than zero.
This allows to specify zero secure interrupts and pass a NULL pointer
for the table address.

The Pine64 Wiki[1] links to a BSP tarball, among other things
containing a dump of an ARM Trusted Firmware source tree with
Allwinner changes on top.
Since the tarball does not contain any version history information
about the changes, this commit is just the diff between the ATF 1.0
release and the files from the Allwinner provided tarball.
The executable flag from many source has been removed.

Assert a valid security state using the macro sec_state_is_valid().
Replace assert() with panic() in those cases that might arise
because of runtime errors and not programming errors.

Refactor the FVP gic code in plat/fvp/fvp_gic.c to be a generic ARM
GIC driver in drivers/arm/gic/arm_gic.c. Provide the platform
specific inputs in the arm_gic_setup() function so that the driver
has no explicit dependency on platform code.
Provide weak implementations of the platform interrupt controller
API in a new file, plat/common/plat_gic.c. These simply call through
to the ARM GIC driver.
Move the only remaining FVP GIC function, fvp_gic_init() to
plat/fvp/aarch64/fvp_common.c and remove plat/fvp/fvp_gic.c
Fixes ARM-software/tf-issues#182
