brcmfmac: rework debugfs functions in the driver
Reworked the debugfs functions in the driver making it easier for other driver parts to add a debugfs entry and keeping the information they want to expose in debugfs private, ie. not in a header. This is accomplished by providing the function brcmf_debugfs_add_entry() in which the caller provides a read function in which they provide the content. The debugfs function will take care of creating the debugfs entry and cleaning up upon removal.
