bbc-i2c: Fix BBC I2C envctrl on SunBlade 2000
Fix regression in bbc i2c temperature and fan control on some Sun systems that causes the driver to refuse to load due to the bbc_i2c_bussel resource not being present on the (second) i2c bus where the temperature sensors and fan control are located. (The check for the number of resources was removed when the driver was ported to a pure OF driver in mid 2008.)
