From: Anson Huang <anson.huang at nxp.com>

Design team change the ahb's clk parent options but did NOT update the DOC
accordingly in time, so the AHB/IPG's clk rate in clk tree is incorrect, AHB is
67.5MHz and IPG is 33.75MHz, but using scope to monitor them, they are actually
135MHz and 67.5MHz, update the clk parent option to make clk tree info correct.
