Subject: [RFC 46/50] staging: vchiq: Get rid of vchi
All the functions that vchi currently provides are a 1:1 mapping to its
vchiq counterparts. Get rid of vchi altogether and use vchiq's on all
services.
In the process also get rid of the vchi directory, as the only remaining
file was a TODO file, which now lives in the parent directory.
