ASoC: SOF: amd: Increase ACP_HW_SEM_RETRY_COUNT value
Host is trying to acquire semaphore lock based on HW_SEM_RETRY_COUNT value which is set to 10 by default. So host will loop for 10 times trying to acquire lock before giving error msg "Failed to acquire HW lock". Though this loop count of 10 is good enough with most of the times but we have observed such failure msg in very few cases(~5 %). Increase ACP_HW_SEM_RETRY_COUNT to avoid such issue and loop for a significant time period before throwing error. We're setting newer loop count to quite higher value of 10K but it's very unlikely that it will loop for this count, since for most of the cases lock will get acquired at much lesser loop iterations.
