soc: qcom: dcc_v2: Add snapshot of the DCC v2 driver 



This is a snapshot of the DCC_v2 driver as of msm-4.14
commit 'f7e2b748'("coresight: stm: Fix master control issue").
The second offset present as part of offset descriptor needs
to take into account the length of the first offset. This patch
fixes the current offset calculation to account for it. This
patch removes the clock support since it's not needed.

Fix sscanf issue to prevent buffer overflow.
