sun5i: Default console to uart0 (v2)

With support for A10s board coming we're going to have a lot of boards
with the console on uart0, so we're going to have a lot of
CONS_INDEX=x statements in boards.cfg anyways.

Given this it makes sense to just default to uart0, since that is a more
logical default and also unifies the console default with sun4i.

Chanes in v2: Don't set CONS_INDEX=2 for sun5i_sdcon.

A10s hack: init uart0 hard and early

This is necessary to get my 2 different A10s boards to cold boot, and
this cannot hurt with A10 / A13 based boards, tested with several A10 boards
as well as with an a13_olinuxino_micro.

wobi-i5: Add new wobo-i5 board

The Wobo i5 is special in that it uses an A10s together with an axp209, rather
then with an axp152.
