[PATCH] ARM: imx_v6_v7_defconfig: Enable RDNIS by default

[PATCH] ARM: imx_v6_v7_defconfig: Enable RDNIS by default

[Alistair Francis]

Supporting Ethernet over USB is very useful for debugging. This allows
debugging systems where the other networking (WiFi or Ethernet) doesn't come
up, while still allowing SSH access.

This is extreamly useful on the reMarkable 2 as it doesn't have UART RX
or a physical ethernet port. If WiFi doesn't work this is the next best
method to access the device.

This should be probably left to users to configure per their needs.  And
configfs might be the best default option.
