From: Honghui Zhang <honghui.zhang at mediatek.com>
Two fixups for mediatek's host bridge:
The first patch fixup class type and vendor ID for MT7622.
The second patch fixup the IRQ handle routine by using irq_chip solution
to avoid IRQ reentry which may exist for both MT2712 and MT7622.
Change since v5:
- Make the comments consistend with the code modification in the first patch.
- Using writew to performing a 16-bit write.
- Using irq_chip solution to fix the IRQ issue.
The v5 patchset could be found in:
https://patchwork.kernel.org/patch/10133303
https://patchwork.kernel.org/patch/10133305
Change since v4:
- Only setup vendor ID for MT7622, igorning the device ID since mediatek's
host bridge driver does not cares about the device ID.
Change since v3:
- Setup the class type and vendor ID at the beginning of startup instead
of in a quirk.
- Add mediatek's vendor ID, it could be found in:

Change since v2:
- Move the initialize of the iterate before the loop to fix an
INTx IRQ issue in the first patch
Change since v1:
- Add the second patch.
- Make the first patch's commit message more standard.
