dsi_clk_init(), which gets the clocks, is called only through platform
driver probe and its failure is a failure of the probe.  Therefore
NULL-ifying specific clocks is pointless and redundant - the PTR_ERR
value stored there won't be used/dereferenced afterwards.  What's more,
variant-specific clock init calls like dsi_clk_init_6g_v2() are not
doing this cleanup.  Dropping redundant code allows later to make this a
bit simpler.
