Several options are presenting themselves on a various boards
where the options are clearly not used. (ie, SPL/TPL options
when SPL or TPL are not defined)
This patch is not attempting to be a complete list of items, but
more like low hanging fruit. In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.
This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

Since we added clk enable_count and prograte clk child enabling
operation to clk parent, so add a new function sandbox_clk_enable_count
to get enable_count for test usage.
And add test code to get the enable_count after we enable/disable
the device clk.

On i.MX8MM, thinking such as clk path
OSC->PLL->PLL GATE->CCM ROOT->CCGR GATE->Device
Only enabling CCGR GATE is not enough, we also need to enable PLL GATE
to make sure the clk path work. So when enabling CCGR GATE,
we could prograte to enabling PLL GATE to make life easier.

As what Linux Kernel 5.3.0 provides when enable/disable clk,
there is an enable_count in clk_core_disable/enable. Introduce
enable_count to track the clk enable/disable count when
clk_enable/disable for CCF. And Initialize enable_count to 0 when
register the clk.
And clk tree dump with enable_count will be supported, it will
be easy for us to check the clk status with enable_count

When support Clock Common Framework, U-Boot use dev for
clk tree information, there is no clk->parent. When
support composite clk, it contains mux/gate/divider,
but the mux/gate/divider is not binded with device.
So we could not use dev_get_uclass_priv to get the correct
clk_mux/gate/divider. So add clk_dev_binded to let

Right now when using clk_of_xlate_default(), clk->data
remains un-initialized because clk_get_bulk() does not
initialize memory on allocation of clock structure.
This can cause problems when data is used to match if
two clocks pointers are exactly the same underlying
clocks, for example.
Fix it by initializing clk->data to 0.

This patch provides code to implement the CCF clock tree in sandbox. It
uses all the introduced primitives; some generic ones are reused, some
sandbox specific were developed.
In that way (after introducing the real CCF tree in sandbox) the recently
added to clk-uclass.c: clk_get_by_id() and clk_get_parent_rate() are tested
in their natural work environment.
Usage (sandbox_defconfig and sandbox_flattree_defconfig):
./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf"

The generic mux clock code for CCF requires reading the clock multiplexer
value from HW registers. As sandbox by design has readl() as no-op it was
necessary to provide this value in the other way.
The new field in the mux structure (accessible only when sandbox is run)
has been introduced for this purpose.

If the CLK_GET_RATE_NOCACHE flag is set - the clk_get_parent_rate()
provides recalculated clock value without considering the cache setting.
This may be necessary for some clocks tightly coupled with power domains
(i.e. imx8), and prevents from reading invalid cached values.

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.
The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.
One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.
If needed, the code can be extended to support the "set" part of the clock
management.

This commit adds the clk_get_by_id() function, which is responsible
for getting the udevice with matching clk->id. Such approach allows
re-usage of inherit DM list relationship for the same class (UCLASS_CLK).
As a result - we don't need any other external list - it is just enough
to look for UCLASS_CLK related udevices.

Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK
without declaring struct clk. As a result it was only accessible by
iterating the udevice's uclass list.
This is a problem for clock code, which operates on pointers to struct
clk (like clk_get_rate()), not udevices.
After this change struct clk is accessible from udevice and udevice from
struct clk.
