A string which did not contain a data format specification should be put

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. This driver also includes clkdev.h even though
it isn't used, so drop it too and add slab.h to make sure
everything still compiles.

The clk-nomadik.o is built for ARCH_NOMADIK -- which is bool, and
hence this code is either present or absent. It will never be
modular, so using module_init as an alias for __initcall can be
somewhat misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

The Nomadik debugfs screws up multiplatform boots if debugfs
is enabled on the multiplatform image, since it's a simple
initcall that is unconditionally executed and reads from certain
memory locations.
Fix this by checking that the driver has been properly
initialized, so a base offset to the Nomadik SRC controller
exists, before proceeding to register debugfs files.

Common clock framework allows to register clock providers to get called
on of_clk_init() by using CLK_OF_DECLARE. This converts nomadik clock
provider to make use of it and get rid of the mach specific clk init
call. As clocks require system reset controller base address to be
initialized each clock driver checks src_base and calls new
nomadik_src_init if required.

nomadik_clk_init currently also maps system reset controller base address
used by clocks and registers a reboot notifier. To allow further cleanup of
nomadik clk setup, this moves system reset controller setup from
nomadik_clk_init to its own function.

This fixes a regression for the Nomadik on the main system
timers.
The Nomadik seemed a bit slow and its heartbeat wasn't looking
healthy. And it was not strange, because it has been connected
to the 32768 Hz clock at boot, while being told by the clock driver
that it was 2.4MHz. Actually connect the TIMCLK to 2.4MHz by
default as this is what we want for nice scheduling, clocksource
and clock event.

The Nomadik clock implementation was a stub just using
fixed clocks.
This implements the clocks properly instead of relying
on them all being on at boot and leaving them all on.
The PLLs are on the top locking to the main chrystal
oscillator, then the HCLK for the peripherals are
below PLL2.
The gated clocks are implemented with zero cells and
given the clock ID as a property of each node, so every
gate need to have its own node in the device tree.
This is because the gate registers contain both HCLK
gates and PCLK gates, where the latter has HCLK as
parent. As can be seen from the register layout, this
is a complete mixup, which means all these gates need
their own node to properly model parent/child relations
for PCLKs apart from the HCLKs.
This driver also adds a helpful debugfs file to inspect
the hardware state of the clock gates.
This is the end result in <debugfs>/clk/clk_summary
after applying a proper device tree:

The Nomadik NAND driver is really just a subset of the existing
FSMC driver, so let's switch over to using that driver instead,
since it handles more variants of this chip. The callbacks for
setting up the chip is doing stuff now handled by the FSMC
driver.
