[ALSA] soc - Fix s3c24xx-i2s LR sync while timer ticks are disabled
When timer ticks are disabled when calling
sound/soc/s3c24xx/s3c24xx-i2s.c:s3c24xx_snd_lrsync
and the LR signal never happens, we loop forever.
This has been observed in the following call chain:
snd_pcm_common_ioctl1 -> snd_pcm_action_lock_irq ->
snd_pcm_action_single
-> snd_pcm_do_resume -> soc_pcm_trigger -> s3c24xx_i2s_trigger
The patch below changes the timeout mechanism to use udelay, which
doesn't need timer ticks.
