[PATCH 2/3] media: vgxy61: Add legacy compatible string

[Benjamin Mugnier <benjamin.mugnier@foss.st.com>]

As the driver has been renamed from 'st-vgxy61' to 'vgxy61', its
compatible string has been updated to reflect this change. Therefore old
device trees will not work anymore.
Add the old driver name as another compatible name to handle the
retro compatibility.
