There is no real distinction here in behaviour, either a clock needs to
be enabled on initialiation or not. The ALWAYS_ENABLED flag was always
intended to only apply to clocks that were physically always on and could
simply not be disabled at all from software. Unfortunately over time this
was abused and the meaning became a bit blurry.

So, we kill off both of all of those paths now, as well as the newer
NEEDS_INIT flag, and consolidate on a CLK_ENABLE_ON_INIT. Clocks that
need to be enabled on initialization can set this, and it will purposely
enable them and bump the refcount up.

This resyncs the rate propagation strategy with the scheme used by the
OMAP clock framework. Child clocks are tracked on a list under each
parent and propagation happens there specifically rather than constantly
iterating over the global clock list.

This adds a followparent_recalc() helper for clocks that just follow the
parent's rate. Switch over the few CPUs that use this scheme for some of
their clocks.

There is nothing in these routines that inherently depends on R0 use.
Given that these routines are inlined, it is rather easy to blow up the
compiler by exhausting the spill class when performing a 64-bit swab.

This presently manifests itself as the following:

fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits':
