ASoC: SOF: Intel: hda: Do not re-enable L1 if disabled before suspend



We have a workaround in place to address a known issue with host DMA
running into xruns when capture streams are running. But when resuming
from Sx, we unconditionally re-enable DMI L1 without taking the
workaround into account and this could lead to xruns when a suspended
capture stream is restarted.

To fix this rename the flag l1_support_enabled to l1_disabled in struct
sof_intel_hda_dev to save the L1 disabled status which can be
set/cleared when we get/put a stream and use the flag to determine if DMI
L1 should enabled or not during the post_fw_run op.
