[ARM] OMAP2/3: Add non-CORE DPLL rate set code and M, N programming

Browse Source 
Add non-CORE DPLL rate set code and M,N programming for OMAP3.
Connect it to OMAP34xx DPLLs 1, 2, 4, 5 via the clock framework.

You may see some warnings on rate sets from the freqsel code.  The
table that TI presented in the 3430 TRM Rev F does not cover Fint <
750000, which definitely occurs in practice.  However, the lack of this
freqsel case does not appear to impair the DPLL rate change.
