Subject: [PATCH net v4 0/2] net: airoha: Improve hwfd buffer/descriptor
 queues setup

Compute the number of hwfd buffers/descriptors according to the reserved
memory size if provided via DTS.
Reduce the required hwfd buffers queue size for QDMA1.

Changes in v4:
- Fix commit log for patch 2/2
- Link to v3: https://lore.kernel.org/r/20250618-airoha-hw-num-desc-v3-0-18a6487cd75e@kernel.org

Changes in v3:
- Target net tree instead of net-next one

Changes in v2:
- Rely on div_u64 to compute number of hw descriptors
- Link to v1: https://lore.kernel.org/r/20250615-airoha-hw-num-desc-v1-0-8f88daa4abd7@kernel.org
