[PATCHv2 0/2] coresight: etm4x: Add support to skip trace unit power up

[Sai Prakash Ranjan]

This series adds support to skip powering up of trace unit on systems
with an errata which stops CPU watchdog counter when power up bit is
set (TRCPDCR.PU = 1). Setting this bit is not required on Qualcomm
Technologies Inc. chipsets where this errata exists since the ETMs
are in the same power domain as their respective CPU cores.
