coresight: Simplify sysfs accessors by using csdev_access abstraction
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.
