Current implementation only checks if the sink is HDCP capable.
In addition, it is required that the source also checks for the
HDCP version supported by the sink prior to initiating HDCP 2.x
authentication sequence.

Add mdio_bus_id and phy_addr to access phy device
instead of scanning mdio bus. It will reduce time
cost during ethernet driver loading.

On consecutive writes in bulk write API, ensure delay
is provided for atleast 100us between each soundwire
master write for WR_DONE status update and reflect
current register value. Also ensure delay in soundwire
master read is present after register address update
and before register value read.

We have observed race condition between inquiring the remote pd state and
indication call back execution. They run asynchronously so we have no
control on their concurrent execution. So to achieve mutual exclusion,
moving the portion of code which result in race condition to indication
acknowledgment routine. Indication acknowledgment is send in separate
thread context which will avoid race condition.

__list_lru_walk_one() acquires nlru spin lock (nlru->lock) for longer
duration if there are more number of items in the lru list. As per the
current code, it can hold the spin lock for upto maximum UINT_MAX entries
at a time. So if there are more number of items in the lru list, then
"BUG: spinlock lockup suspected" is observed in the below path -

Fix this lockup by reducing the number of entries to be shrinked from the
lru list to 1024 at once. Also, add cond_resched() before processing the
lru list again.
