mpc85xx: use LCRR_DBYP define instead of raw constant
Using the raw value of 0x80000000 directly in the code can lead to "count the zeros" bugs like that fixed in commit 718e9d13b98 ("MPC85xxCDS: Fix missing LCRR_DBYP bits for 66-133MHz LBC") Change all existing raw values to use the symbolic value of LCRR_DBYP instead.
