i2c-host updates for v6.16
Cleanups and refactorings
- Many drivers switched to dev_err_probe()
- Generic cleanups applied to designware, iproc, ismt, mlxbf,
npcm7xx, qcom-geni, pasemi, and thunderx
- davinci: declare I2C mangling support among I2C features
- designware: clean up DTS handling
- designware: fix PM runtime on driver unregister
- imx: improve error logging during probe
- lpc2k: improve checks in probe error path
- xgene-slimpro: improve PCC shared memory handling
- pasemi: improve error handling in reset, smbus clear, timeouts
- tegra: validate buffer length during transfers
- wmt: convert binding to YAML format
Improvements and extended support:
- microchip-core: add SMBus support
- mlxbf: add support for repeated start in block transfers
- mlxbf: improve timer configuration
- npcm: attempt clock toggle recovery before failing init
- octeon: add support for block mode operations
- pasemi: add support for unjam device feature
- riic: add support for bus recovery
New device support:
- MediaTek Dimensity 1200 (MT6893)
- Sophgo SG2044
- Renesas RZ/V2N (R9A09G056)
- Rockchip RK3528
