d5e136a21b clk: samsung: Register clk provider only after registering its all clocks
Ensure the clock provider is not registered until after all its related
clocks were created and are ready to use. Currently there are races
possible and any (of_)clk_get() call right after a clock provider's
clk_init_cb callback call may fail.

44ff0254b8 clk: exynos5420: Remove aclk66_peric from the clock tree description
The "aclk66_peric" clock is a gate clock with a whole bunch of gates
underneath it.  This big gate isn't very useful to include in our
clock tree.  If any of the children need to be turned on then the big
gate will need to be on anyway.  ...and there are plenty of other "big
gates" that aren't described in our clock tree, some of which shut off
collections of clocks that have no relationship in the hierarchy so
are hard to model.

"aclk66_peric" is causing earlyprintk problems since it gets disabled
as part of the boot process, so let's just remove it.

Strangely (and for no good reason) this clock is exported as part of
the common clock bindings.  Remove it since there are no in-kernel
device trees using it and no reason anyone out of tree should refer to
it either.

6520e968ee clk: exynos5420: Add 5800 specific clocks
Exynos5800 clock structure is mostly similar to 5420 with only
a small delta changes. So the 5420 clock file is re-used for
5800 also. The common clocks for both are seggreagated and few
clocks which are different for both are separately initialized.

976face4b4 clk/samsung: add support for multiple clock providers
Samsung CCF helper functions do not provide support to
register multiple Clock Providers for a given SoC. Due to
this limitation, SoC platforms are not able to use these
helpers for registering multiple clock providers and are
forced to bypass this layer.

This layer is modified accordingly to enable the support
for multiple clock providers.

Clock file for exynos4, exynos5250, exynos5420, exynos5440,
S3c64xx, S3c24xx are also modified as per changed helper functions.
