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.
