i2c: designware: Some broken DSTDs use 1MiHz instead of 1MHz

commit 682c6c2188f39d13548ccdc89c9888fbcb547889 upstream.

At least the Acer Iconia Tab8 / aka W1-810 uses 1MiHz instead of
1MHz for one of its busses, fix this up to 1MHz instead of failing
the probe of that bus.

This fixes the accelerometer on the Acer Iconia Tab8 not working.
