Configure GPIOs for I2S based on revision/card settings 

With RPi model B+, assignment of the I2S GPIO pins has changed.
This patch uses the board revision to auto-detect the GPIOs used
for I2S. It also allows sound card drivers to set the GPIOs that
should be used. This is especially important with the Compute
Module.
