Bug description:
  SRU Justification

  [Impact]

  * Inclusion of upstream f6028eeeb5e4: "coresight: core: Disable helpers for 
devices that fail to enable" added two calls to coresight_disable_helpers() 
with an additional path parameter, which is not available in the current 
function call, which only accepts coresight_disable_helpers(struct 
coresight_device *csdev). This causes the kernel to fail to build when 
coresight is enabled.
  * Additionally, upstream 53b9e2659719: "coresight: holding cscfg_csdev_lock 
while removing cscfg from csdev" caused build failures with a spinlock type 
change.

  [Fix]

  * Clean cherry-pick of upstream 3c03c49b2fa5: "Coresight: Introduce a new 
struct coresight_path"
  * Backport of upstream 080ee83cc361: "Coresight: Change functions to accept 
the coresight_path"
  * Clean cherry-pick of upstream 26f060c106f6: "coresight: change 
coresight_device lock type to raw_spinlock_t"

  [Test Plan]

  * Compile tested

  [Regression potential]

  * Changes are localized to coresight. Possible regressions could
  result in unexpected behavior of coresight module.
