acpi_pcihp_get_bsel implements functionality of object_property_get_int for
specific property named ACPI_PCIHP_PROP_BSEL, but fails to decrement object's
reference counter properly. Rewriting it using generic object_property_get_int
serves two purposes: reducing code duplication and fixing memory leak.

v1 -> v2:
Keep acpi_pcihp_get_bsel, but rewrite it using object_property_get_int and
validate returned value.
