[PATCH v2] ARM: multi_v7_defconfig: Enable CONFIG_RPMSG_TTY

The RPMsg TTY implements an inter-processor communication with a standard
TTY interface on top of the RPMsg framework.
This driver is a generic RPMsg client that can run on different platforms.

By enabling the RPMSG_TTY driver as module in multi_v7_defconfig, it makes
possible to automatically probe the rpmsg_tty driver by the RPMsg bus,
when the support of the RPMsg service is dynamically requested by the
co-processor firmware.
