- RCE Rx queue limit size is 16, no point to have 32 elements long queue
in kernel.
- Pass kernel's queue length to RCE when opening a channel so it can be
validated (to not exceed RCE max depth)
- validate image buffers IOVA addresses and buffer length before queuing

Upstream commit aa7a9275ab81 ("PM: sleep: Suspend async parents after
suspending children") triggers a suspend issue on Tegra234 Jetson
Orin Nano boards because it had reordered the suspend of devices with
async suspend enabled with respect to some other devices. This commit
is present in Linux v6.16 kernels.
The same issue was observed with the cypd4226 Type-C controller used on
other Jetson platforms and due to its dependencies on other devices it
is necessary to disable async suspend to fix the issue [0]. Fix suspend
for Tegra234 Jetson Nano platforms by disabling 'async' suspend for the
fusb301 device. Note that it is safe to disable this for all kernel
versions.

This is for avoiding kernel hang when DCE FW fails to respond.
Failures of IPC call will return -ERESTARTSYS or -ETIMEOUT, which
will be handled by caller functions:

This is module export symbol and caller have the responsibility
of checking return value.
2. DCE FSM event handler
Error return will change back to previous state.

This change adds the support for programming streamids to
allow tsec fw on t264 to access PA at a low privilege level.
It also includes the synchronization logic to communicate
with the fw regarding completion of stream id programming
so that the fw can go ahead and initialize itself.
In addition to this, the mailbox used for communicating init done
from tsec fw to ccplex is changed from NV_PTSEC_FALCON_MAILBOX0 to
NV_PTSEC_MAILBOX1 since CCPLEX does not have access to the former from
t26x onwards. Hence falcon based mailboxes are used for tsec-psc comms
and non-falcon ones for tsec-ccplex comms (stream id comms and init done).

The tegra_dai_fixup function was incorrectly updating the format mask
when S24_LE format was requested and DAI has 32-bit sample width incase
the stream on that DAI is already running.
S24_LE format uses 32-bit physical width on the DAI interface, but
the format mask should remain as S24_LE to maintain proper format
negotiation. The fix adds a check to skip format mask updates when
S24_LE is requested and DAI sample_bits is 32.
This resolves issues with RT5640 and other codecs that support
24-bit audio formats on Tegra platforms.

When switching the governor to nvhost_pogdov or switching back to other
governors, we will need to lock the devfreq lock to prevent triggering
DVFS cycle from other paths.
The nvhost_pod_target_freq callback will be called when triggering the
DVFS cycle. However, the callback expects governor data is already
allocated and initialized. We need to synchronize the operations when we
switch the governor so that DVFS cycle can only be triggered when
governor data is ready.

Fix riace condition between host1x_syncpt_alloc()
and host1x_syncpt_put() by using kref_put_mutex()
instead of kref_put() + manual mutex locking.
This ensures no thread can acquire the
syncpt_mutex after the refcount drops to zero
but before syncpt_release acquires it.
This prevents races where syncpoints could
be allocated while still being cleaned up
from a previous release.
Remove explicit mutex locking in syncpt_release
as kref_put_mutex() handles this atomically.
