[PATCH 4/6] clk: Add Kconfig option to build all generic clk drivers

[Mark Brown]

Currently drivers for the generic clk subsystem must be selected by
platforms using them in order to enable build. When doing development on
the API or generic build time testing it is useful to be able to build
unused drivers in order to improve coverage so supply a Kconfig option
which allows this.
