Our CPUidle state save restore has some bugs which are triggered for an ETM with
system instructions (e.g. ETE). This is a series of fixes to address them.

Changes since v1:
 - Fix inverted check for drvdata->csdev for Patch 1 (Yabin)
 - Remove Data trace register access macro cases (Mike Leach)
 - Fix QFILT field definition (Yabin)
 - (New patch) Fix Resource pair register access, reported-by Yabin

Suzuki K Poulose (4):
  coresight: etm4x: Do not hardcode IOMEM access for register restore
  coresight: etm4x: Do not save/restore Data trace control registers
  coresight: etm4x: Safe access for TRCQCLTR
  coresight: etm4x: Fix access to resource selector registers
