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.
