fix(qemu): fix EL3-SPMC data store alignment

Browse source 
With PLAT=qemu, the EL3-SPMC data store is provided as an array of
uint8_t and implicitly with a 1 byte alignment. But the way the data
store is used it must have a larger alignment, so change to double-word
alignment for maximum compatibility.
