The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.

The crypto SRAM, used by the armada 370 cpuidle code to workaround a bug
in the BootROM code, requires the crypto clk to be up and running.
Flag the crypto clk as IGNORE_UNUSED until we add the proper
infrastructure to define the crypto SRAM in the DT and reference the crypto
clk in this SRAM node.

Even if not documented in the datasheet, the Armada 370 SoC can actually
gate the CESA (crypto engine) clock.
Add an entry in the gating_desc table to be able to reference the CESA
gateclk in the crypto node.

This commit activates the SSCG deviation correction for the Armada
370. It uses the optional function introduced by the commit "clk:
mvebu: Fix clk frequency value if SSCG is enabled".
Without this fix the deviation measured on a Mirabox was of a few
second each hour, whereas with this fix it was reduced at around
50ppm (around 4s per day).

Init order of CLK_OF_DECLARE'd drivers depends on compile order.
Unfortunately, clk_of_init does not allow drivers to return errors,
e.g. -EPROBE_DEFER if parent clocks have not been registered, yet.
To avoid init order woes for MVEBU clock drivers, we take care of
proper init order ourselves. This patch joins core-clk and gating-clk
init to maintain proper init order.

This patch fixes the tclk frequency array for the Armada-370 SoC.
This bug has been introduced by commit 6b72333d
("clk: mvebu: add Armada 370 SoC-centric clock init").
A wrong tclk frequency affects the following drivers: mvsdio, mvneta,
i2c-mv64xxx and mvebu-devbus. This list may be incomplete.
About the mvneta Ethernet driver, note that the tclk frequency is used
to compute the Rx time coalescence. Then, this bug harms the coalescence
configuration and also degrades the networking performances with the
default values.

This is moving core clock and clock gating init for Armada 370 to
its own file and adds a Kconfig option. Also init functions are added
and declared so they get called on of_clk_init.
