As per hardware recommendation, for every capture stream completion
following operations need to be done in order to reflect the actual
data that is received in position buffer.

1. Wait for 20us before reading the DMA position in buffer once the
interrupt is generated for stream completion.
2. Read any of the register to flush the DMA position value. This is
dummy read operation.

When creating the codec dai, use sig_bits to update the max bps based
on the codec capability. So both the link DMA and codec format will be
calculated based on DAI sig_bits.

So update the sig_bits with converter capability and use the sig_bits

For calculating the HDA DMA format, use the max_bps supported by the
DAI caps instead of fixing it to 32/24. For host DMA the Max bps support
is 32, but in case of link DMA, this depends on the codec capability.

When module size > DMA buffer size, driver copies first chunk and waits
for the BDL complete interrupt. BDL complete interrupt never occurs and
wait time expires as module load IPC is not send to start the DMA from
DSP.

To fix the above issue need to follow the below steps:
1. After copying the first chunk, send the module load IPC to start the
DMA.
2. Wait for the BDL interrupt. Once interrupt is received, copy the
next chunk.
3. Continue step 2 till all bytes are copied.
4. When all the bytes are copied (bytes_left = 0), wait for module load
IPC response
5. Handled module load IPC response messages, check the load module IPC
response and wake up the thread to complete module load.
