[PATCH] ASoC: cs4271: Increase delay time after reset

[pascal.huerst]

From: Pascal Huerst <pascal.huerst@gmail.com>

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.
