Unfortunately it's vendor specific stuff, only vendor prefixes are
documented on uefi.org.
And it's fine to use an already existing ID for the component from the
same company.
The thing is that this is a really discrete component from TI on Intel
Galileo board.

I'm not against the clean up in code, but I don't think it is good to
encourage users to use PRP0001 when the ACPI ID is already allocated
(doesn't matter by whom).

So, I would recommend to leave the change, but rephrase the commit
message to avoid PRP0001 mentioning.
