 battery switch-over

Hi Alexandre,

Having a way to dynamically change the configuration would definitely
be helpful in most cases. I decided to go with a DT property because
in the case this patch tries to solve (the cubox-i) there isn't simply
any other option - the default mode won't work due to the missing hw
components. So, I thought that by defining it as a DT property it
could somehow be locked to the hardware definition.
Keep me posted

Regards

PS: Sorry for the second message, forgot to disable html and the
