Merge branch 'dpaa-cleanups'

Sean Anderson says:

====================
net: dpaa: Cleanups in preparation for phylink conversion (part 2)

This series contains several cleanup patches for dpaa/fman. While they
are intended to prepare for a phylink conversion, they stand on their
own. This series was originally submitted as part of [1].

[1] https://lore.kernel.org/netdev/20220715215954.1449214-1-sean.anderson@seco.com

Changes in v5:
- Reduce line length of tgec_config
- Reduce line length of qman_update_cgr_safe
- Rebase onto net-next/master

Changes in v4:
- weer -> were
- tricy -> tricky
- Use mac_dev for calling change_addr
- qman_cgr_create -> qman_create_cgr

Changes in v2:
- Fix prototype for dtsec_initialization
- Fix warning if sizeof(void *) != sizeof(resource_size_t)
- Specify type of mac_dev for exception_cb
- Add helper for sanity checking cgr ops
- Add CGR update function
- Adjust queue depth on rate change
