[PATCH v2 1/7] clk/qcom: move from mach-snapdragon

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.
