dt-bindings: clock: samsung: remove define with number of clocks

Number of clocks supported by Linux drivers might vary - sometimes we
add new clocks, not exposed previously. Therefore these numbers of
clocks should not be in the bindings, as that prevents changing them.
Remove it entirely from the bindings, once Linux drivers stopped using
them.

clk: samsung: Add clk ID definitions for the CPU parent clocks

Add clock ID definitions for the CPU parent clocks for SoCs
which don't have such definitions yet. This will allow us to
reference the parent clocks directly by cached struct clk_hw
pointers in the clock provider, rather than doing clk lookup
by name.

clk: samsung: exynos5420: Add definition of clock ID for mout_sw_aclk_g3d

This patch adds ID for the mout_sw_aclk_g3d (SW_CLKMUX_ACLK_G3D) clock,
mostly for internal use in the CMU driver. It will allow to avoid the
__clk_lookup() call when setting up the clock during the clock provider
initialization.

clk: exynos5420: Add IDs for clocks used in DISP1 power domain

When a power domain is powered off on Exynos5420 SoC, the input clocks of
the devices attached to this power domain are re-parented to oscclk and
restored to the original parent after powering on the power domain.

So a reference to the input and parent clocks for the devices attached to
a power domain are needed to be able to do the re-parenting. The DISP1 pd
includes modules which uses the following clocks:

ACLK_200_DISP1 (MIXER and HDMILINK)
ACLK_300_DISP1 (FIMD1)
ACLK_400_DISP1 (Internal Buses)

Each of these clocks are generated as the output of a clock mux so add an
ID for all of these clock muxes and their parents to be referenced in the
DISP1 power domain device node.

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.
