that way it would be possible to test a DSDT pointed by
64bit X_DSDT field in FADT.
PS:
it will allow to enable testing arm/virt board, which sets
only newer X_DSDT field.

v2:
add 'val = le32_to_cpu(val)' even if it doesn't necessary
it works as reminder that value copied from table is in
little-endian format (Philippe Mathieu-Daudé <phi...@redhat.com>)
