ACPICA: acpiexec: Add option to specify an object initialization file.

This option (-fi) allows the specification of a file that is used
to specify initialization values for individual namespace objects.
Each line in the file is in the format:

<ACPI pathname> <Integer Value>

This patch only affects acpiexec which is not in the Linux kernel.
