Currently only peripheral clocks are supported for Broadcom
platforms that use Kona style CCUs for clocking.  This series
adds support for bus clocks as well.

One motivation for doing this is that there exist peripheral clocks
that cannot be configured without having first enabled a related
bus; the peripheral clock registers are simply inaccessible if the
bus clock is not enabled.  So adding bus clock support allows such
clocks to be usable.

This also imposes a new requirement, however--that the bus clock
be enabled *before* the clock that depends on it.  For this, we
define the notion of a "prerequisite" clock.  If a clock has a
prerequisite specified, that prequisite clock will be initialized
first.  For now this only affects startup-time initialization.

These patches are based on Mike Turquette's current "clk-next"
branch.  They are available here:
