Subject: [PATCH AUTOSEL 4.18 069/131] PCI: mobiveil: Fix struct
 mobiveil_pcie.pcie_reg_base address type

From: Lorenzo Pieralisi <lorenzo.pieralisi@....com>

[ Upstream commit af3f606e0bbb6d811c50b7b90fe324b07fb7cab8 ]

The field pcie_reg_base in struct mobiveil_pcie represents a physical
address so it should be of phys_addr_t type rather than void __iomem*;
this results in the following compilation  warnings:

drivers/pci/controller/pcie-mobiveil.c: In function
'mobiveil_pcie_parse_dt':
drivers/pci/controller/pcie-mobiveil.c:326:22: warning: assignment makes
pointer from integer without a cast [-Wint-conversion]
  pcie->pcie_reg_base = res->start;
                      ^
drivers/pci/controller/pcie-mobiveil.c: In function
'mobiveil_pcie_enable_msi':
drivers/pci/controller/pcie-mobiveil.c:485:25: warning: initialization
makes integer from pointer without a cast [-Wint-conversion]
  phys_addr_t msg_addr = pcie->pcie_reg_base;
                         ^~~~
drivers/pci/controller/pcie-mobiveil.c: In function
'mobiveil_compose_msi_msg':
drivers/pci/controller/pcie-mobiveil.c:640:21: warning: initialization
makes integer from pointer without a cast [-Wint-conversion]
  phys_addr_t addr = pcie->pcie_reg_base + (data->hwirq * sizeof(int));

Fix the type and with it the compilation warnings.
