[PATCH] clk: tegra: Don't enable PLLs during early boot

[Peter De Schrijver <pdeschrijver@nvidia.com>]

The PLL code relies on udelay() which is not available when CCF is
initialized. Hence we can't enable any PLL during this phase.

Stephen,

Can you confirm this is ok for the audio drivers?

We used to be lucky that this has worked up to now, but I will introduce some
changes to the pll lock check code which cause this to fail due to the
slight differences in timing.
