implicit cast to structure uint8_t member didn't raise error when
assigning value from incorrect enum, but when using build_append_gas()
(next patch) it will error out with (clang):
  implicit conversion from enumeration type 'AmlRegionSpace'
  to different enumeration type 'AmlAddressSpace'
fix cast error by using correct AML_AS_SYSTEM_MEMORY enum
