-OMAP34xx ES2 TRM Delta G to H states that the divider for DPLL1_FCLK and 
-DPLL2_FCLK can divide by 4 in addition to dividing by 1 and 2. Encode this 
-into the OMAP3 clock framework.

-Fix DPLL jitter correction programming.  Previously, 
-omap3_noncore_dpll_program() stored the FREQSEL jitter correction 
-parameter to the wrong register.  This caused jitter correction to be set 
-incorrectly and also caused the DPLL divider to be programmed incorrectly.
-
-Also, fix DPLL divider programming.  An off-by-one error existed in 
-omap3_noncore_dpll_program(), causing DPLLs to be programmed with a higher 
-divider than intended.
