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
