Change Intel PT's branch stack support to use thread stacks. The
advantages of using branch stack support from the thread-stack are:
1. the branches are accumulated separately for each thread
2. the branch stack is cleared only in between continuous traces
This helps pave the way for adding branch stacks to regular events, not
just synthesized events as at present.
While the 2 approaches are not identical, in simple cases the results
can be identical e.g.
Before:
# perf record --kcore -e intel_pt// uname
# perf script --itrace=i10usl -F+brstacksym,+addr,+flags > cmp1.txt
After:
# perf script --itrace=i10usl -F+brstacksym,+addr,+flags > cmp2.txt
# diff -s cmp1.txt cmp2.txt
Files cmp1.txt and cmp2.txt are identical

Intel PT already has support for creating branch stacks for each context
(per-cpu or per-thread). In the more common per-cpu case, the branch stack
is not separated for different threads, instead being cleared in between
each sample.
That approach will not work very well for adding branch stacks to
regular events. The branch stacks really need to be accumulated
separately for each thread.
As a start to accomplishing that, this patch adds support for putting
branch stack support into the thread-stack. The advantages are:
1. the branches are accumulated separately for each thread
2. the branch stack is cleared only in between continuous traces
This helps pave the way for adding branch stacks to regular events, not
just synthesized events as at present.

Enable build testing and configuration control of the common clk
framework so that more code coverage and testing can be done on the
common clk framework across various architectures. This also nicely
removes the requirement that architectures must select the framework
when they don't use it in architecture code.
There's one snag with doing this, and that's making sure that randconfig
builds don't select this option when some architecture or platform
implements 'struct clk' outside of the common clk framework. Introduce a
new config option 'HAVE_LEGACY_CLK' to indicate those platforms that
haven't migrated to the common clk framework and therefore shouldn't be
allowed to select this new config option. Also add a note that we hope
one day to remove this config entirely.

This is because the implementation of of_platform_device_destroy() is
inside an #ifdef CONFIG_OF_ADDRESS section of drivers/of/platform.c.
This driver already depends on OF being enabled, so let's tighten that
constrain a little more so that it depends on OF_ADDRESS instead. This
way we won't try to build this driver on platforms that don't have this
function.
