Prepare for the coming implementation by GCC and Clang of the __counted_by

As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

Wh

clk: Introduce clk_hw_determine_rate_no_reparent()

Some clock drivers do not want to allow any reparenting on a given
clock, but usually do so by not providing any determine_rate
implementation.

Whenever we call clk_round_rate() or clk_set_rate(), this leads to
clk_core_can_round() returning false and thus the rest of the function
either forwarding the rate request to its current parent if
CLK_SET_RATE_PARENT is set, or just returning the current clock rate.

This behaviour happens implicitly, and as we move forward to making a
determine_rate implementation required for muxes, we need some way to
explicitly opt-in for that behaviour.

Fortunately, this is exactly what the clk_core_determine_rate_no_reparent()
function is doing, so we can simply make it available to drivers.

clk: Mark a fwnode as initialized when using CLK_OF_DECLARE() macro

We already mark fwnodes as initialized when they are registered as clock
providers. We do this so that fw_devlink can tell when a clock driver
doesn't use the driver core framework to probe/initialize its device.
This ensures fw_devlink doesn't block the consumers of such a clock
provider indefinitely.

However, some users of CLK_OF_DECLARE() macros don't use the same node
that matches the macro as the node for the clock provider, but they
initialize the entire node. To cover these cases, also mark the nodes
that match the macros as initialized when the init callback function is
called.

An example of this is "stericsson,u8500-clks" that's handled using
CLK_OF_DECLARE() and looks something like this:

clocks {
compatible = "stericsson,u8500-clks";

prcmu_clk: prcmu-clock {
#clock-cells = <1>;
};

prcc_pclk: prcc-periph-clock {
#clock-cells = <2>;
};

prcc_kclk: prcc-kernel-clock {
#clock-cells = <2>;
};

prcc_reset: prcc-reset-controller {
#reset-cells = <2>;
};
...
};

This patch makes sure that "clocks" is marked as initialized so that
fw_devlink knows that all nodes under it have been initialized. If the
driver creates struct devices for some of the subnodes, fw_devlink is
smart enough to know to wait for those devices to probe, so no special
handling is required for those cases.

clk: Add generic sync_state callback for disabling unused clocks

There are unused clocks that need to remain untouched by clk_disable_unused,
and most likely could be disabled later on sync_state. So provide a generic
sync_state callback for the clock providers that register such clocks.
Then, use the same mechanism as clk_disable_unused from that generic
callback, but pass the device to make sure only the clocks belonging to
the current clock provider get disabled, if unused. Also, during the
default clk_disable_unused, if the driver that registered the clock has
the generic clk_sync_state_disable_unused callback set for sync_state,
skip disabling its clocks.

clk: asm9260: use parent index to link the reference clock

Rewrite clk-asm9260 to use parent index to use the reference clock.
During this rework two helpers are added:

- clk_hw_register_mux_table_parent_data() to supplement
clk_hw_register_mux_table() but using parent_data instead of
parent_names

- clk_hw_register_fixed_rate_parent_accuracy() to be used instead of
directly calling __clk_hw_register_fixed_rate(). The later function is
an internal API, which is better not to be called directly.

clk: Introduce the clk_hw_get_rate_range function

Some clock providers are hand-crafting their clk_rate_request, and need
to figure out the current boundaries of their clk_hw to fill it
properly.

properly.

Let's create such a function for clock providers.
