Registers for adjusting the spread spectrum clocking (SSC) have been
added. As reported by the TI spruhl7x RM, SSC is supported only for LCD
and MPU PLLs, but the PRCM_CM_SSC_DELTAMSTEP_DPLL_XXX and
PRCM_CM_SSC_MODFREQDIV_DPLL_XXX registers, as well as the enable field
in the PRCM_CM_CLKMODE_DPLL_XXX registers are mapped for all PLLs (CORE,
MPU, DDR, PER, DISP, EXTDEV).
