dmaengine: JZ4780: Add support for the JZ4755.

The JZ4755 has 4 DMA channels per DMA unit, two idential DMA units.

The JZ4755 has the similar DMA engine to JZ4725b and it has the
same bug as JZ4725b, see commit a40c94be2336.
At least the JZ_SOC_DATA_BREAK_LINKS flag make it work much better,
although not ideal.
