Clock drivers don't belong here, move them to the right place and declutter mach-snapdragon a bit.
To de-couple these drivers from specific "target" platforms, add additional config options to enable each clock driver gated behind a common CLK_QCOM option and enable them by default for the respective targets. This will make future work easier as we move towards a generic Qualcomm target.
