[PATCH v7 0/3] arm64: dts: add i.MX95 and EVK board

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.

This patchset is just a minimal support for i.MX95. After this patchset
is accepted, a following patchset will include more nodes and features.
