Kumar Gala 202d94875c 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).
