target-arm: use extended address bits from supersection short descriptor
Since ARMv7 with LPAE support, a supersection short translation table
descriptor has had extended base address fields which hold bits 39:32 of
translated address. These fields are IMPDEF in ARMv6 and ARMv7 without
LPAE support.
