dma-engine: sun4i: Add a quirk to support different chips

Browse source

Allwinner suniv F1C100s has similar DMA engine to sun4i. Several
registers has different addresses. Total dma channels, endpoint counts
and max burst counts are also different.

In order to support F1C100s add a quirk structure to hold IC specific
data.
