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
