[SeaBIOS] [PATCH 1/4] acpi: generate mixed asl/aml listing

Use iasl -l flag to produce a mixed listing, where a
source line is followed by matching AML.
Since we use a preprocessed input, this generates long lines with
multiple commands per line. To make it possible to match
AML to source exactly, split the input that we supply iasl,
with each command on a separate line.
