clk: sunxi-ng: a33: Add offset and minimum value for DDR1 PLL N factor
The DDR1 PLL on the A33 is an oddball amongst the A33 CCU clocks.
It is a clock multiplier, with the effective multiplier in the
range of 12 ~ 255 and no offset between the multiplier value and
the value programmed into the register.
Implement the zero offset and minimum value of 12 for this clock.
