x86: doc: Update to include Intel Bayley Bay board instructions

Browse Source 
Update existing documentation to mention Intel Bayley Bay board
instructions, an additional Bay Trail based board to MinnowMax.

This also adds a minor change to QEMU section to indicate clearly
the instructions are for bare mode.

For Minnowboard MAX, we can reuse the same ME firmware above, but for flash
descriptor, we need get that somewhere else, as the one above does not seem to
work, probably because it is not designed for the Minnowboard MAX. Now download
