PCI: Keep both device and resource name for config space remaps
Follow the rule taken in commit 35bd8c07db2c ("devres: keep both device
name and resource name in pretty name") and keep both device and resource
names while requesting memory regions for PCI config space to prettify e.g.
/proc/iomem output:
Before (DWC Host Controller):
18b00000-18b01fff : dbi
18b10000-18b11fff : config
18b20000-18b21fff : dbi
18b30000-18b31fff : config
After:
18b00000-18b01fff : 18b00000.pci dbi
18b10000-18b11fff : 18b00000.pci config
18b20000-18b21fff : 18b20000.pci dbi
18b30000-18b31fff : 18b20000.pci config
