ASoC: cs4271: Increase delay time after reset
commit 74ff960222d90999508b4ba0d3449f796695b6d5 upstream.
The delay time after a reset in the codec probe callback was too short,
and did not work on certain hw because the codec needs more time to
power on. This increases the delay time from 1us to 1ms.
