To support ADSP SVA on wcd934x, dedicated backend dailink needs
to be created. Add the dailink associating the specific cpu dai
and the MAD codec dai.

Stack canary relies on getting early random values. However, the
software random number generator is initialized relatively late in the
boot process making the stack canary very predictable.
Enable the hardware supported random number generator until
the software number generator is enabled later in boot.

Stack canary initialization involves getting a random number.
Getting this random number may involve accessing caches or other
architectural specific features which are not available until
after the architecture is setup. Move the stack canary initialization
later to accommodate this.

Parse the Detailed Timing Descriptors of both EDID blocks for
resolutions. Check if the resolution is already added in local
data base. Also, add tolerance to fps and pclk variations for
a give resolution so that EDID parser can capture all the
resolutions correctly as published by the sink's EDID.

The existing support for generating random numbers relied on
a hacked up version of CONFIG_ARCH_RANDOM and was prone to
scheduling while atomic bugs due to needing to take a mutex.
We don't actually need the additional randomness all the time,
the pool just needs to be initialized with some amount of random
data to avoid getting the same result each time. Switch to
this method for initializing the random pool.

Currently, the software random number generator is not initialized
until relatively late in the boot process. Software that relies on
random numbers early will not be reliable. Entropy sources are
available early but not early enough for some use cases which means
that moving the software random number generation earlier is not an
option. As an alternate solution, implement the functions associated
with CONFIG_ARCH_RANDOM. These functions currently make a call into
trustzone to get reliable random numbers. The functions are disabled
once the regular random number generator is sufficiently reliable.

While flushing debug queues, avoid touching message queues.
Bleeding message queues here can discard FW responses and
forward threads may timeout by not receiving them. This can
cause confusion about timeouts. Hence don't touch message
queues unless you process and send them to forward thread.

Previously memory retention and preiph control are only set when
device enters/exits idle power collapse mode. The memory retention
and periph setting will remain ON when device is actually in
suspend state, which will cause unnecessary power consumption.
This change updates those setting for both idle power collapse cases
and suspend/resume case. With this change, the memory retention and
periph will be set to OFF in suspend case to optimize power consumption.
