mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.
In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It
should be safe as the fifth bit was defined as reserved and set to 0.
Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.
