We've already reduced this significantly from the original 41k LoC
down to ~14.7k by stripping out non-essential features such as
exception handling, memory logging, devlink, statistics, debug
tracing, and others.

We even removed some arguably necessary features (PM, mdlog,
throughput optimizations) that we plan to submit as follow-up
series.

Note that the line count may slightly increase in v2, as we plan
to add missing kdoc comments based on review feedback.

For reference, the t7xx driver (two generations older, simpler HW)
had an initial submission of ~11.3k LoC [1]. The t9xx hardware is
more complex, so we believe being in a similar range is reasonable.

We'd like to keep the driver functional and reviewable in its
current scope. Do you have any suggestions on how we could further
reduce the size while maintaining a working initial submission?
