Define and export a new function __clk_get_debug which returns the debugfs
directory entry pointer. This can be used by clock providers to add debugfs
entries which are not related to a specific clock type. Examples include the
ability to measure the rate of a clock. It can also be used by modules to
create new debugfs entries. This is useful if you want to expose features
for testing which can potentially cause system instability such as allowing
to change a clock's rate from userspace.
