clk: actually call the clock init before any other callback of the clock

Browse Source 
[ Upstream commit f6fa75ca91 ]

 __clk_init_parent() will call the .get_parent() callback of the clock
 so .init() must run before.

Fixes: 541debae0a ("clk: call the clock init() callback before any other ops callback")
