[PATCH v3 01/13] OMAP: hwmod: allow hwmod to provide address space accessible from SDMA

[Kishon Vijay Abraham I <kishon@ti.com>]

Adds support for resource API to get address space info other than just MPU.
The drivers can now use platform_get_resource_byname() to get resource of
type 'IORESOURCE_MEM' by name.
