[PATCH 1/1] tools/libacpi: clear out compilation warnings

[Ariel Otilibili <Ariel.Otilibili-Anieli@xxxxxxxxxx>]

From: Ariel Otilibili <otilibil@xxxxxxxxxx>

* While compiling ASLs, iasl puts out deprecation warnings

```
tools/libs/light/mk_dsdt --debug=y --maxcpu any --dm-version none >> 
tools/libs/light/dsdt_pvh.asl
/usr/bin/iasl -vs -p tools/libs/light/dsdt_pvh.tmp -tc 
tools/libs/light/dsdt_pvh.asl

tools/libs/light/dsdt_pvh.asl     40:         Processor ( PR00, 0, 0x0000b010, 
0x06 ) {
Warning  3168 -                                                                 
  ^ Legacy Processor() keyword detected. Use Device() keyword instead.

tools/libs/light/dsdt_pvh.asl     64:         Processor ( PR01, 1, 0x0000b010, 
0x06 ) {
Warning  3168 -                                                                 
  ^ Legacy Processor() keyword detected. Use Device() keyword instead.
```

* since 6.0, the ACPI specs have deprecated the keyword Processor
* the deprecation is mentioned in Rev. History, Issue 1232
* instead, ACPI advices to use the keyword Device
* after the fix, the warnings are cleared out.
