[PATCH v2 2/5] clk: qcom: gcc-msm8998: add SSC-related clocks

[michael.srba@seznam.cz]

From: Michael Srba <Michael.Srba@seznam.cz>

 This patch adds four clocks which need to be manipulated in order to
 initialize the AHB bus which exposes the SCC block in the global address
 space.

 Care should be taken not to write to these registers unless the device is
 known to be configured such that writing to these registers from Linux
 is permitted.
