ACPICA: Interpreter: Add warning if 64-bit constant appears in 32-bit table.
Some ASL compilers allow 64-bit constants within a 32-bit table
(DSDT version == 1). When encountered, emit a warning that the
constant will be truncated to 32 bits. This is potentially a
serious problem in the ACPI table(s).
