Updated mach-types update

[H Hartley Sweeten]

Hello Russell,

I will be submitting the platform init for MACH_VISION_EP9307 for review soon.  I
have a bit more testing to do before it will be ready.  Possibly by the end of the
week or early next week.

Should this submission include the necessary patch to add back:

+vision_ep9307          MACH_VISION_EP9307      VISION_EP9307           1578

Or do I just need to inform you so that it can be added back to mach-types?

Thanks,
Hartley
