of/irq: Convert of_msi_map_id() callers to of_msi_xlate()
With the introduction of the of_msi_xlate() function, the OF layer
provides an API to map a device ID and retrieve the MSI controller
node the ID is mapped to with a single call.
of_msi_map_id() is currently used to map a deviceID to a specific
MSI controller node; of_msi_xlate() can be used for that purpose
too, there is no need to keep the two functions.
Convert of_msi_map_id() to of_msi_xlate() calls and update the
of_msi_xlate() documentation to describe how the struct device_node
pointer passed in should be set-up to either provide the MSI controller
node target or receive its pointer upon mapping completion.
