The drivers can use platform_get_resource_byname() to get resource of type 'IORESOURCE_MEM' by name so that it need not rely on the order to get the proper resource.

The idea of that patch is to allow hwmod to provide address space accessible from SDMA (though L3). Hence the suppression of the MPU. In the future, we might even be able to provide the address for the DSP or the IPU viewpoint
