spi: airoha: add dma support

This patch speed up cache reading/writing/updating opearions.
It was tested on en7523/an7581 and some other Airoha chips.

It will speed up
 * page reading/writing without oob
 * page reading/writing with oob
 * oob reading/writing (significant for UBI scanning)

The only know issue appears in a very specific conditions for en7523 family
chips only.
