b1220e2e7f CRIS v10: Update kernel/io_interface_mux.c
Fixed a bug where two interfaces using pins in the same pin group could
not be allocated at the same time even if there where no pin collisions.

Change all restore and returns into goto exit pattern.

5f526d1467 CRIS v10: Setup serial port 2 to avoid accidental TXD pulse on startup.
If serial port 2 is used, select it in R_GEN_CONFIG.
If serial port 2 is used, setup the control registers for the port.
This is done to avoid a pulse on the TXD line during start up,
which could disturb some units.

Also, remove useless CVS id and log.
