[PATCH 11/26] hw/intc/arm_gicv3_its: Use 1ULL when shifting by (DTE.SIZE + 1)

[Peter Maydell]

The DTE.SIZE field is 5 bits, which means that DTE.SIZE + 1
might in theory be 32. When calculating 1 << (DTE.SIZE + 1)
use 1ULL to ensure that we don't do this arithmetic at 32 bits
and shift the 1 off the end in this case.
