Add OF_DEV_AUXDATA for slink driver for Tegra20 and Tegra30
board dt files.
Set the parent clock of slink controller to PLLP and configure
clock to 100MHz.

I would rather hard-code the addresses there (e.g. write literally
0x7000d400), and hence not have to edit iomap.h;

As I wrote for V1:

Lets not add [or change] anything to iomap.h; we're trying to remove it.
Instead, just put the raw address in the AUXDATA; I assume that's the
only place these defines end up being used...

Aside from that, this series looks fine.
