ACPICA: iasl: add ASL conversion tool
ACPICA commit c04d310039d3e0ed1cb62876fe7e596fbc75ab01
ACPICA commit a65c1df7e6b4bad8e37df822018c40c6c446add9
The key feature of this utility is that the original comments within
the input ASL files are preserved during the conversion process, and
included within the converted ASL+ file -- thus creating a transparent
conversion of existing ASL files to ASL+ (ASL 2.0)
This patch is an automatic generation of the ASL converter commit,
Linux kernel isn't affected by the functionality provided in this
commit, but requires the linuxized changes to support future ACPICA
release automation.
