AmlSetFixedArgument() accepts an index equal to the fixed argument count.
The count is an exclusive upper bound, so this permits an out-of-bounds
write to the FixedArgs array.
Require the index to be strictly less than the fixed argument count.

AmlSetFixedArgument() attaches NewNode to an AML object but does not
currently verify that the node is detached. Passing an already attached
node could leave the AML tree in an inconsistent state.
Require non-NULL argument nodes to be detached before attaching them.
Continue accepting NULL because callers use it to clear a fixed
argument.

ACPI 6.4, s6.4.2.9 "End Tag":
"This checksum is generated such that adding it to the sum of all the data
bytes will produce a zero sum."
"If the checksum field is zero, the resource data is treated as if the
checksum operation succeeded. Configuration proceeds normally."
To avoid re-computing checksums, if a new resource data elements is
added/removed/modified in a list of resource data elements, the AmlLib
resets the checksum to 0.
This patch also refactors the AmlAppendRdNode() function by getting the
last Resource Data node directly instead of iterating over all the
elements of the list of Resource Data node.

The AML tree is composite and has the following node types:
- Root node.
- Object node.
- Data node.
These nodes are part of the Fixed Arguments or the Variable
arguments list in the AML tree.
The AML tree interface provides functions to manage the fixed
and the variable argument nodes in the AML tree.
