OMAP3630: DSS2: Updating MAX divider value

OMAP3630: DSS2: Updating MAX divider value

In DPLL4 M3, M4, M5 and M6 field width has been increased by 1 bit in 3630.
So the max divider value that can be achived will be 32 and not 16.
In 3630 the functional clock is x1 of DPLL4 and not x2. Hence multiplier 2
is removed.
