[PATCH 6/8] drm/bochs: phase 3: provide a custom ->atomic_commit implementation

[John Hunter <zhjwpku@gmail.com>]

From: Zhao Junwang <zhjwpku@gmail.com>

This supports the asynchronous commits, required for page-flipping
Since it's virtual hw it's ok to commit async stuff right away, we
never have to wait for vblank.
