PCI: mediatek: Silence 'set affinity failed' warning 

JIRA: https://issues.redhat.com/browse/RHEL-67693
Upstream Status: 63e4794cde79c2724f9c02abe8a46be70a5b90df

commit 63e4794cde79c2724f9c02abe8a46be70a5b90df
Author: Marek Vasut <marek.vasut+renesas@mailbox.org>
Date:   Tue Jul 23 15:27:07 2024 +0200

    PCI: mediatek: Silence 'set affinity failed' warning

    Use MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity() unset and allows
    migrate_one_irq() to exit right away, without warnings like this:

      IRQ...: set affinity failed(-22)

    Remove the .irq_set_affinity() implementation that is no longer needed.
