Subject: [PATCH v1 3/4] ACPI: PCI: Drop ACPI_PCI_COMPONENT that is not used any more

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

After dropping all of the code using ACPI_PCI_COMPONENT drop the
definition of it too and update the documentation to remove all
ACPI_PCI_COMPONENT references from it.
