Paulo Zanoni 46a5ae9f82 drm/i915: WARN is the DP aux read or write is too big 
So far we control everything and nothing exceeds the current limits,
but (i) we never think about these limits when reviewing patches, (ii)
not all the callers check the return values and (iii) if we ever hit
any of these messages, we'll have to fix the code that added the bad
message.

The current limit for these messages is 20 since we only have 5 data
registers on all the current gens.

The checks inside intel_dp_aux_native_{write,read} are to prevent
buffer overflows. The check inside intel_dp_aux_ch is to prevent
writing past our 5 data registers.
