DC5 and DC6 counter register tells about residency of DC5 and DC6.
Added the same in debugfs file.
v2 : Remove csr_version check.
Added generic check regarding DC counters for Gen9 onwards. (Rodrigo)
v3 : Simplified gen checks. (Chris)
v4 : Simplified "if" ladder for multiple gens.
v5 : Removed unnecessary comment.
