Merge tag 'memory-controller-drv-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into soc/drivers

Memory controller drivers for v6.17

1. Several cleanups: Use dev_fwnode() in OMAP GPMX, convert
   arm,pl172.txt DT bindings to DT schema, use
   syscon_regmap_lookup_by_phandle_args() wrapper, correct kerneldoc.

2. Mediatek MT8186 SMI: Extend hardware bandwidth limits to fix VENC
   hardware during stress testing.

3. Broadcom brcmstb_memc: Add additional fallback compatible and
   simplify device driver matching.  The change comes from Broadcom
   SoC maintainer (Florian Fainelli), thus its ABI impact is
   acknowledged.
