[PATCH v1 2/4] spi: dw-pci: apply pci_bar and re-use pci_name

[Andy Shevchenko]

Nevertheless pci_bar is 0 let's explicitly use it when map IO regions. While
here, use pci_name instead of dev_name.

[PATCH v1 3/4] spi: dw-pci: convert to use dev_pm_ops

[Andy Shevchenko]

Convert system PM callbacks to use dev_pm_ops. In addition remove the PCI calls
related to a power state since the bus code cares about this already.
