Add gpt_3m clock for i.mx6qdl, as gpt can source clock
from OSC, some i.MX6 series SOCs has fixed divider of
8 for gpt clock, so here add a fix clk of gpt_3m.
i.MX6Q TO1.0 has no gpt_3m option, so force it to be
from ipg_per.

change log from v2 -> v3:
re-initialize gpt_3m to ipg_per on i.MX6Q TO1.0
