When the binding was written all "future" platforms required three
clocks, so the default compatible (qcom,scm) was defined to require
this. But as history shows all "future" platforms actually lack required
clocks. Given how the binding is written these compatibles have to be
added as an exception to the default.
Refactor the description of compatible to define that a platform
compatible should be given, followed by the fallback of qcom,scm. Also
refactor the description of the clocks in a way that this does not need
to be updated as new platform specific compatibles are added.

The current cpsw usage for cpsw-phy-sel is undocumented but is used for
all the boards using cpsw. And cpsw-phy-sel is not really a child of
the cpsw device, it lives in the system control module instead.
Let's document the existing usage, and improve it a bit where we prefer
to use a phandle instead of a child device for it. That way we can
properly describe the hardware in dts files for things like genpd.

Meelis Roos reported a {menu,n}config regression:
"I have libncurses devel package installed in the default system
location (as do 99%+ on actual developers probably) and in this
case, pkg-config is useless. pkg-config is needed only when
libraries and headers are installed in non-default locations but
it is bad to require installation of pkg-config on all the machines
where make menuconfig would be possibly run."
For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.
Fixes: 4ab3b80159 ("kconfig: check for pkg-config on make {menu,n,g,x}config")

the buffer
b) change the argument order to have the buffer as first argument
c) add a new argument telling the function if the message was
transferred. This allows the function to be used also in cases
where setting up DMA failed, so the buffer needs to be freed without
syncing to the message buffer.
Also convert the only user.
