acpi: add pre-process step to capture arg counts for all function decls
...
Since the ACPI standard allows forward function declarations this step
is required so we can properly parse the argument list for function
invocations. Contrary to other AML entities, method invocations do not
include any sort of pkgLength information so unless we track the
expected argument count for each function, our parser will not be able
to figure out where the argument list ends.
