Subject: [PATCH 5.16 190/200] PCI: mt7621: Remove unused function pcie_rmw()

From: Sergio Paracuellos <sergio.paracuellos@...il.com>

commit c035366d9c9fe48d947ee6c43465ab43d42e20f2 upstream.

Function pcie_rmw() is not being used at all and can be deleted. Hence get
rid of it, which fixes this warning:

  drivers/pci/controller/pcie-mt7621.c:112:20: warning: unused function 'pcie_rmw' [-Wunused-function]

Fixes: 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver")
