Serge Semin 6bce9ec9e0 dmaengine: dw-edma: Fix readq_ch() return value truncation

[ Upstream commit 5fdca4a995bcd4cf61bda40af154a730589dc524 ]

Previously, readq_ch() did a 64-bit readq(), but truncated the result by
storing it in the u32 "value".  Change "value" to u64 to avoid the
truncation.

Note: the method is currently unused, so the bug hasn't caused any problem
so far.
