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 v2:
Merge two patches into one.

I'm not sure it's worth enforcing just the last clock name. Just do:

enum: [ peri_mem, top_133m ]

And key in the top level.

OK, I'll use "enum" to add the new clock name in the next version.

Thanks.
