OK, so since this patch is basically just splitting the file into
multiple parts, you can ignore most of my review comments for this patch
and consider them as input for things in future cleanup patches.

One comment below:

What I meant was the body of this function is:

tegra2_usb_phy_open:
if (ulpi)
do a bunch of ULPI stuff
else
do a bunch of UTMI stuff

It's seems it'd be simpler to split this into two functions:

tegra2_usb_ulpi_phy_open:
do a bunch of ULPI stuff

tegra2_usb_utmi_phy_open:
do a bunch of UTMI stuff

... and have the code that initializes the ops assign the appropriate
one of those two functions into the open op, just like it does for
all/most other ops.

Still, this may come under the same argument as above; fuel for future
cleanup since the existing code already works this way?
