[PATCH] VT binding: Make VT binding a Kconfig option

To enable this feature, CONFIG_VT_HW_CONSOLE_BINDING must be set to 'y'.  This
feature will default to 'n' to minimize users accidentally corrupting their
virtual terminals.

+         The virtual terminal is the device that interacts with the physical
+         terminal through console drivers. On these systems, at least one
+         console driver is loaded. In other configurations, additional console
+         drivers may be enabled, such as the framebuffer console. If more than
+         1 console driver is enabled, setting this to 'y' will allow you to
+         select the console driver that will serve as the backend for the
+         virtual terminals.

+         See <file:Documentation/console/console.txt> for more
