d9652b4e8a ACPICA: iASL/Disassembler: Add option to ignore NOOP opcodes/operators
Implemented for both the compiler and the disassembler.  Often,
the NOOP opcode is used as padding for packages that are changed
dynamically by the BIOS. When disassembled, these NOOPs will
cause syntax errors. This option causes the disassembler to ignore
the NOOP opcode, and it also causes the compiler to ignore NOOP
statements as well.

9cea6249c9 ACPICA: Resources: Split interrupt share/wake bits into two fields.
These two bits are merged at the external interface level for the
IRQ, Interrupt, and GpioInt resource descriptors. However, these
bits are logically independent and there is no need to keep them
merged internally. Therefore, this change splits the bits into
"sharable" and "wake capable" fields within the resource manager.
This simplifies drive code that needs to examine these bits.
