ACPI: property: Replicate DT-aligned u32 properties from DisCo for Imaging

MIPI DisCo for Imaging defines properties for camera sensors that
functionally align with DT equivalents.

Replicate these properties in the ACPI device swnodes so the code
using the corresponding DT properties already does not need to be
updated to deal with their MIPI counterparts directly.

The replicated properties are:

	"mipi-img-clock-frequency" -> "clock-frequency"
	"mipi-img-led-max-current" -> "led-max-microamp"
	"mipi-img-flash-max-current" -> "flash-max-microamp"
	"mipi-img-flash-max-timeout" -> "flash-max-timeout-us"
