vc4: Add a note for the future about texture latency calculation.

Debugging a shader-db reported cycle count regression from the tex
coalescing, I eventually figured out that the texture latencies were
totally bogus.  Really fixing it will probably involve mirroring
vc4_qir_schedule.c's texture fifo management here.
