Subject: [PATCH 1/4] remoteproc/davinci: Switch to platform_get_resource_byname()

The davinci remoteproc driver currently uses the platform_get_resource()
API for retrieving the IOMEM resources. Switch this function to use the
platform_get_resource_byname() API instead in preparation for adding the
DT support so that the binding can be agnostic of the IOMEM resource
order.
