[PATCH v2 2/5] clk: qcom: common: introduce qcom_cc_sync_state()

[Brian Masney <bmasney@redhat.com>]

Several qcom clk providers currently have a sync_state helper set to
icc_sync_state(). With an upcoming change to the clk framework, if
sync_state is not defined for the device, then the clk framework sets it
to clk_sync_state().

Clk providers that require their own sync_state will need to call the
framework level clk_sync_state(). Let's introduce a new common helper
qcom_cc_sync_state() that calls icc_sync_state() and clk_sync_state().
