I think this was wrong to start with: The aliases should be in the per-board
.dts file and only list the ones that are actually connected to the outside.
Otherwise the numbering won't match what's written on the board.

At least in the case of DRA7 boards, they are not written specifically
since they come out over onboard FTDI usb2serial.
This will at least ensure that /dev/ttyO9 will always point to uart10
no matter the board, instead of having ttyO0 always pointing to
console serial port no matter the board (and having to guess which
figure out it actually was aliased to).

It seems that having the UART numbering make sense is a good reason
to apply this one. So applying into omap-for-v3.19/dt.
