ALSA: AACI: fix timeout duration
Relying on the access time of peripherals is unreliable - it depends on the speed of the CPU and the bus. On Versatile Express, these timeouts were expiring, causing the driver to fail. Add udelay(1) to ensure that they don't expire early, and adjust timeouts to give a reasonable margin over the response times. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
