For bonded configuration mode, the low speed parallel clock output of the master CGB
is used and the local CGB within each channel is bypassed. For non-bonded
configurations, the master CGB also provides a high speed serial clock output to each
channel without bypassing the local CGB within each channel.
The x6 clock lines also drive the xN clock lines which route the clocks to the
neighboring transceiver banks.
