PCI hotplug: clean up acpi_run_hpp()
This patch cleans up acpi_run_hpp() and follows the style of acpi_run_hpx():
- remove unnecessary METHOD_NAME__HPP #define
- use ACPI_ALLOCATE_BUFFER rather than evaluating _HPP twice
- validate _HPP package length (defined as 4 by the spec)
- avoid ref to undefined data if FW provides < 4 elements
- remove temporary nui[] array
