Revert "dm: ns16550: Add support for reg-offset property"

Browse Source 
This reverts commit d9a3bec682.

While this is a correct change to do long term it unfortunately breaks a
number of platforms that are using pdata and not named struct members so
they are getting all of their data after 'base' incorrect.
