Subject: [PATCH] arm64: dts: imx95: correct a55 power-domains

From: Peng Fan <peng.fan@....com>

The A55 power domains is for SCMI performance usage, so for device power
on/off. Correct the power-domains entry to use scmi_perf not scmi_devpd.

Fixes: 5e3cbb8e4256 ("arm64: dts: freescale: add i.MX95 basic dtsi")

V1:
 The reason that it not fail with scmi_devpd is the driver only use the index,
 not use the phandle, so it works before. But since the phandle was wrong, so
 correct it.
