Pass 'cookie' parameter to interrupt handler in BL3-1
The interrupt handling routine in BL3-1 expects a cookie as its last parameter which was not being passed when invoking the interrupt handler in BL3-1. This patch fixes that by passing a dummy cookie parameter in the x3 register. Fixes ARM-software/tf-issues#171 Change-Id: Ic98abbbd9f849e6f1c55343e865b5e0a4904a1c5
