MT8188 and MT8195 are ARM platform SoCs with the same PCIe IP as MT8192.

Also add new clock name "peri_mem" since the MT8188 and MT8195 use clock
"peri_mem" instead of "top_133m".

Changes in v3:
Use enum property to add the new clock name.

Changes in v2:
Merge two patches into one.

You have one item, so this is just const. Or enum if  you expect it to
grow soon.

This requires allOf:if:then restricting it further per variant.

I see Rob proposed that way, so skip this comment.

It makes sense, I'll remove this "items" and just keep the const item
in the next version.

Thanks.
