mb/siemens/mc_apl{1,2,3,5,6}: Provide I2C timings for 400 kHz

The I2C bus at which the external RTC is attached to is operated at
standard speed (100 kHz) at coreboot runtime. The OS can choose to run it
at fast speed since it uses its own driver and controller setup.

Report additional bus timings for fast mode so that OS can do it right.
