staging: vc04_services: Drop vchiq_log_debug() in favour of dev_dbg

Drop vchiq_log_debug() macro which wraps dev_dbg(). Introduce the usage
of dev_dbg() directly.

Meanwhile at it, drop the usage of __func__ from the logs.
Dynamic debug supports this via the 'f' decorator flag.

Remove the entry from TODO regarding custom logging. VC04 is now
aligned according to the standard kernel logging mechanisms.

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.
