Add a minimal i.MX95 dtsi and EVK board dts. i.MX95 has a M33 running SCMI firmware that supports pinctrl/power/perf/clock and etc. imx95-pinfunc.h will trigger checkpatch error, that is expected and same as other i.MX platforms. [1] has been merge to https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git/log/?h=for-next In v6, I added back a dependency on pinctrl, because [1] has got A-b/R-b from Maintainers, so it would be soon got merged. There will be dtbs_check error before [1] got landed. With [1] merged, there will be no dtbs_check error. [1] https://lore.kernel.org/all/20240521-pinctrl-scmi-imx95-v1-0-9a1175d735fd@xxxxxxx/ This patchset is just a minimal support for i.MX95. After this patchset is accepted, a following patchset will include more nodes and features.
