Manivannan Sadhasivam 875bdd2f9b PCI: endpoint: pci-epf-vntb: Fix the incorrect usage of __iomem attribute 
[ Upstream commit 61ae7f8694 ]

__iomem attribute is supposed to be used only with variables holding the
MMIO pointer. But here, 'mw_addr' variable is just holding a 'void *'
returned by pci_epf_alloc_space(). So annotating it with __iomem is clearly
wrong. Hence, drop the attribute.

This also fixes the below sparse warning:

  drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17:    expected void [noderef] __iomem *mw_addr
