MIPS: pb44: Fix i2c-gpio GPIO descriptor table

BugLink: http://bugs.launchpad.net/bugs/1807469
commit 326345f995a83e326fa2e01d54bfa9a6a307bd4d upstream.

I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".

But several had it set to >=0 which gives the names
"i2c-gpio.0", "i2c-gpio.1" ...

Fix the one affected board in the MIPS tree. Sorry.
