ether_get_tx_ts, pdata->tx_ts_ref_cnt is an atomic variable
that is used as a mutex in this function and should not return 0
if the function fails to acquire the mutex.
The workqueue is scheduled when the return value of the
judgment function is <0. If one CPU core execution softirq
is running in ether_get_tx_ts function and another CPU core
softirq also calls ether_get_tx_ts function to get hardware
timestamp, then the acquisition of mutex fails and return 0.
After returning 0, the workqueue is not scheduled.
The timestamp cannot be obtained in time. So ether_get_tx_ts
should returns -1 on failure to acquire the mutex.

Interconnect support for multimedia engines is disable for Linux v6.2
kernels. Rather than always disabling interconnect support for these
kernels, we just need to ensure the necessary upstream kernel patches
are in place for Linux v6.2 kernels. Therefore, enable interconnect
support for all kernels.

Add a callback function host1x_syncpt_fence_signaled() to
.signaled op under host1x_syncpt_fence_ops.
.signaled is a optional operation. The change here is a performance
improvement and acts as temporary workaround for sync_file code not
calling enable_signaling.
