ppc/85xx: Fix LCRR_CLKDIV defines
For some reason the CLKDIV field varies between SoC in how it interprets
the bit values.
All 83xx and early (e500v1) PQ3 devices support:
clk/2: CLKDIV = 2
clk/4: CLKDIV = 4
clk/8: CLKDIV = 8
Newer PQ3 (e500v2) and MPC86xx support:
clk/4: CLKDIV = 2
clk/8: CLKDIV = 4
clk/16: CLKDIV = 8
Ensure that the MPC86xx and MPC85xx still get the same behavior and make
the defines reflect their logical view (not the value of the field).
