remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver

Provide a basic driver to control Cortex M4 co-processor found on NXP i.MX7D and i.MX6SX. Currently it is able to resolve addresses between M4 and main CPU, start and stop the co-processor. Other functionality is not provided or test. This driver was tested on NXP i.MX7D and expected to work on i.MX6SX as well.
