+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.
