Aaand the hack patch I sent is crap... We can't skip the x2 clock path,
as the dpll4_mNx2_ck clock nodes handle enable/disable bit, which is
present on 3630 also.

I think the best and simplest way to fix this is by setting the
multiplier in the dpll4_mNx2_mul_ck nodes to 1. I don't know why I
didn't think of it yesterday.

I have a bunch of other patches needed to get the clocks right, so I'll
send a series separately a bit later today.
