rpmsg: char: Export alias for RPMSG ID rpmsg-raw from table
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).
