* Fix PS/2 keyboard problem caused by statically initialized variable 

pointing to a location in flash

* Fix INCA-IP clock calculation: 400/3 = 133.3 MHz, not 130.

======================================================================
* Fix PS/2 keyboard problem caused by statically initialized variable
pointing to a location in flash
* Fix INCA-IP clock calculation: 400/3 = 133.3 MHz, not 130.
* The PS/2 mux on the BMS2003 board needs 450 ms after power on
before we can access it; add delay in case we are faster (with no
CF card inserted)
