hw/arm/smmuv3: Fix potential integer overflow (CID 1432363)
Use the BIT_ULL() macro to ensure we use 64-bit arithmetic.
This fixes the following Coverity issue (OVERFLOW_BEFORE_WIDEN):
CID 1432363 (#1 of 1): Unintentional integer overflow:
overflow_before_widen:
Potentially overflowing expression 1 << scale with type int
(32 bits, signed) is evaluated using 32-bit arithmetic, and
then used in a context that expects an expression of type
hwaddr (64 bits, unsigned).
