There's a reason the word "platform" is in cc_platform_has(). Initially
we wanted to distinguish attributes of the different platforms. So even
if y'all don't like CC_ATTR_PARAVISOR, that is what distinguishes this
platform and it *is* one platform.

So call it CC_ATTR_SEV_VTOM as it uses that technology or whatever. But
call it like the platform, not to mean "I need this functionality".

I can live with that.  There's already a CC_ATTR_GUEST_SEV_SNP, so it
would at least not be too much of a break from what we already have.
