Comment (by Joel Sherrill):

 Any chance this change broke it and no one noticed?

     serial/ns16550: Fix precision clock synthesizer

     The precision clock synthesizer support broke the driver on the QorIQ
     P1020.  On this device the Alternate Function Register is accessed
 with
     DLAB == 1 instead of the FIFO Control Register (FCR).  Restructure the
     code to account for this.
