Eros Q Native: Add Original Firmware Boot option

Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.

A couple notes:

- When booting from the menu, the recovery menu disappears, then
  reappears before going into the OF.

- You need to hold the play button for like a half second after the
  blue light comes on in order to get into the OF.

The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out
for now.
