[PATCH v2] hw/display/tcx: Mark the VRAM dirty upon reset

[Philippe Mathieu-Daudé]

When resetting we don't want to *reset* the dirty bitmap,
we want to *set* it to mark the entire VRAM dirty due to
the memset() call.

Replace memory_region_reset_dirty() by tcx_set_dirty()
which conveniently set the correct ranges dirty.
