clk: Add support for Arm's Versatile Express OSC clock generators
The Arm Versatile Express and Juno development boards contain an
OSC clock generator that can be accessed through the Versatile
Express config bus. The generators are quite often being controlled
by some MCU and the config bus offers a uniform way of exposing them.

buildman: Avoid hanging when the config changes
Something has changed in the last several month such that when buildman
builds U-Boot incrementally and a new CONFIG option has been added to the
Kconfig, the build hanges waiting for input:
Test new config (NEW_CONFIG) [N/y/?] (NEW)
Since binamn does not connect the build's stdin to anything this waits on
stdin to the build thread, which never comes. Eventually I suspect all the
threads end up in this state and the build does not progress.
Fix this by passing /dev/null as input to the build. That way, if there is
a new CONFIG, the build will stop (and fail):
