dmaengine: PL08x: remove circular_buffer boolean from channel data
Circular buffers are not handled in this way; we have a separate API call now to setup circular buffers. So lets not mislead people with this bool. Acked-by: Linus Walleij <linus.walleij@linaro.org> Tested-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
