Subject: clk: sunxi-ng: a33: Add offset and minimum value for DDR1 PLL N factor

From: Chen-Yu Tsai <[email protected]>

[ Upstream commit 68f37d862403e8f95337b2eca90af15d0b8cd5d7 ]

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.
