Improve the msi code:
1. Add proper error handling.
2. Move dw_pcie_msi_init() from each users to designware host to solve
msi page leakage in resume path.

Since v1:
- add proper error handling patches.
- solve the msi page leakage by moving dw_pcie_msi_init() from each
users to designware host

Jisheng Zhang (5):
PCI: dwc: Call dma_unmap_page() before freeing the msi page
PCI: dwc: Check alloc_page() return value
PCI: dwc: Rename dw_pcie_free_msi to dw_pcie_msi_deinit
PCI: dwc: Skip PCIE_MSI_INTR0* programming if MSI is disabled
PCI: dwc: Move dw_pcie_msi_init() from each users to designware host
