Fix power supply presence information

While testing missing power supply, the bottom power supply in the MRW
is labeled as psu1, which would obviously map to powersupply1, but when
that supply was removed and a power on attempted, the call out was for
powerupply0. A simple rename of the labels does not work out right, due
to the filenames, so swizzling the GPIO and I2C information.

Resolves: openbmc/openbmc#2563
