Changes since v1:
* Keep existing signed offset value types until the very last commit and then remove them all at once
* Also split out usages of read_pair() and read32() into separate functions in the last commit
* Whitespace fixes
* Replaced any touched scnprintf() with sysfs_emit()
======
The intent of this change is to reduce the large number identical of functions created by macros for sysfs accessors. It's possible to re-use the same function but pass in the register to access as an argument. This reduces the size of the coresight modules folder by 244KB.
The first two patches are refactors to simplify and remove some dead code, and the second two are the changes to use a shared function.
Testing =======
No changes in any of the outputs:
