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 a40c94be

.
At least the JZ_SOC_DATA_BREAK_LINKS flag make it work much better,
although not ideal.
