Takashi Iwai 990afef90e ASoC: intel: Fix PM and non-atomic crash in bytcr drivers 
commit 6e4cac23c5 upstream.

The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry
the ignore_suspend flag, and this prevents the suspend/resume working
properly while the stream is running, since SST core code has the
check of the running streams and returns -EBUSY.  Drop these
superfluous flags for fixing the behavior.

Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE
definitions, which leads to the kernel Oops at suspend/resume like:

  BUG: scheduling while atomic: systemd-sleep/3144/0x00000003

   ....

This patch addresses these appropriately, too.
