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.

The ability to use a custom function in this sysfs show function isn't used so remove it.
No functional changes.

Sorry for the slightly out-of-scope reply, but I think you could also take the opportunity to replace scnprintf() calls with sysfs_emit() calls, if you think it is worth it.
Thanks, German

The coresight_device struct is available in the sysfs accessor, and this contains a csdev_access struct which can be used to access registers. Use this instead of passing in the type of each drvdata so that a common function can be shared between all the cs drivers.
No functional changes.

Currently each accessor macro creates an identical function which wastes space in the text area and pollutes the ftrace function names. Change it so that the same function is used, but the register to access is passed in as parameter rather than baked into each function.
