Platform order is important when looping through the list of guc
firmware blobs since we use it to prevent loading a blob for a newer
platform onto an older one. Move PVC after ADL.

Shouldn't we be moving the ADL platforms (graphics versions 12.0) higher
than DG1 (12.10) and DG2 (12.50) too?

question then would be:  would we be ordering them by gt
version?  Or by when they were introduced?

I think it makes more sense to be by when they were introduced as a
platform in the driver.

	1) what about media/display?
	2) allow us to always be appending in the enum and elsewhere in
	the driver.
