arm-bsp/trusted-firmware-a: corstone1000: Add patch for removing dependency of GICC frame for GICv3

GICC registers are not defined for GICv3. Trusted-Firmware-A throws error when
GICC register address is not defined even for GICv3. Adding patch
to handle this in Trusted-Firmware-A.

+Subject: [PATCH] fix(css): don't require the GICC frame to be defined on GICv3
+
+It's used for GICv2 operation, which won't happen with v3. CSS will
+always use USE_GIC_DRIVER with the correct version so we can rely on
+that to skip passing the GICC frame.
+
