dmaengine: coh901318: return ssize_t for coh901318_debugfs_read
The file_operations.read expects return as ssize_t, so update
coh901318_debugfs_read to return ssize_t to fix the warning:
drivers/dma/coh901318.c:1369:2: warning: initialization from incompatible pointer type [enabled by default]
.read = coh901318_debugfs_read,
