pm_clk_remove() is currently unused.

It hasn't been used since at least 2011 when it was renamed from
pm_runtime_clk_remove() by commit 3d5c30367cbc ("PM: Rename clock
management functions")

Remove it.

Note that the __pm_clk_remove() is still used and is left in.

PM: clk: make pm_clk_add_notifier() take a const pointer

The driver core wants to work with const struct bus_type, so there's no
reason that pm_clk_add_notifier() should not also do the same thing,
considering that it just passes the pointer off to the driver core which
is expecting a const *.

PM: runtime: add devm_pm_clk_create helper

A typical code pattern for pm_clk_create() call is to call it in the
_probe function and to call pm_clk_destroy() both from _probe error path
and from _remove function. For some drivers the whole remove function
would consist of the call to pm_remove_disable().

Add helper function to replace this bolierplate piece of code. Calling
devm_pm_clk_create() removes the need for calling pm_clk_destroy() both
in the probe()'s error path and in the remove() function.

PM / clk: Add support for adding a specific clock from device-tree

Some drivers using the PM clocks framework need to add specific clocks
from device-tree using a name by calling the functions
of_clk_get_by_name() and then pm_clk_add_clk(). Rather than having
drivers call both functions, add a helper function of_pm_clk_add_clk()
that will call these functions so drivers can call a single function
to add a specific clock from device-tree.

PM / clk: Add support for obtaining clocks from device-tree

The PM clocks framework requires clients to pass either a con-id or a
valid clk pointer in order to add a clock to a device. Add a new
function of_pm_clk_add_clks() to allows device clocks to be retrieved
from device-tree and populated for a given device. Note that it is
not necessary to make the compilation of this new function dependent
upon CONFIG_OF because there are stubs functions for the device-tree
APIs used.

In order to handle errors encountered when adding clocks from
device-tree, add a function pm_clk_remove_clk() to remove any clocks
(using a pointer to the clk structure) that have been added
successfully before the error occurred.

The existing pm_clk_add() allows to pass a clock by con_id. However,
when referring to a specific clock from DT, no con_id is available.

Add pm_clk_add_clk(), which allows to specify the struct clk * directly.
The will will increment refcount on clock pointer, so the caller has
to use clk_put() on clock pointer when done.
