Add support for the Anbernic 351V. Just like the 353 series the
underlying vendor is unknown/unmarked (at least not visible in a
non-destructive manner). The panel had slightly different init
sequences and timings in the BSP kernel, but works fine with the
same ones used in the existing driver. The panel will not work without
the inclusion of the MIPI_DSI_CLOCK_NON_CONTINUOUS flag, and this flag
prevents the 353 series from working correctly, so a new compatible
string is added.

Tested colors and timings using modetest and all seem to work identical
to the 353 otherwise.
