Andy Shevchenko ffe843b182 dmaengine: dw: Fix FIFO size for Intel Merrifield
Intel Merrifield has a reduced size of FIFO used in iDMA 32-bit controller,
i.e. 512 bytes instead of 1024.

Fix this by partitioning it as 64 bytes per channel.

Note, in the future we might switch to 'fifo-size' property instead of
hard coded value.
