Subject: [PATCH v1 04/13] PCI: pciehp: Configure hot-added display devices

We configure cache line size and other settings of hot-added devices, e.g.,
based on ACPI _HPP or _HPX methods.  Previously we skipped this
configuration for display devices, but there is no spec requirement for
that.

Remove the check so we configure display devices the same way we configure
other devices.

See also ac81860ea073 ("PCI: hotplug: pciehp: Removed check for hotplug of
display devices").
