Bus is not always 1

[abkfenris]

When building powercape.c and ina219.c for Beaglebone Black running a Resin.io Debian container, I had to change int i2c_bus = 1; to int i2c_bus = 2; as the devices were on the i2c-2 bus instead of the i2c-1 bus.

I have a patch if you want to make the fixes programatically (git apply fix_powercape.patch).

Whoops, I forgot to put the "bus" option in the powercape utility ala the ina219 util. And then I went and used "-b" for "enter bootloader". Hmmm....
