[ Upstream commit 6e29c30d8ddea6109ea7e0b9f17e7841df0794ea ]
Module aliases are used by userspace to identify the correct module to load for a detected hardware. The currently supported RPMSG device IDs for this module include "rpmsg-raw", but the module alias is "rpmsg_chrdev".
Use the helper macro MODULE_DEVICE_TABLE(rpmsg) to export the correct supported IDs. And while here, to keep backwards compatibility we also add the other ID "rpmsg_chrdev" so that it is also still exported as an alias.
This has the side benefit of adding support for some legacy firmware which still uses the original "rpmsg_chrdev" ID. This was the ID used for this driver before it was upstreamed (as reflected by the module alias).
