For drivers that use multiple resources of the same type, converting those 
to use platform_get_resource_byname() does indeed seem appropriate.

By the way, the same IP block design can exist on platforms with different 
device data formats.  For example, the PowerVR SGX core[1] is present on 
many ARM SoCs and on Intel Poulsbo designs.  The Poulsbo systems are 
presumably using ACPI/SFI *SDT tables.  So it seems unwise to couple 
drivers to any specific external device data format.
