[RESEND/PATCH] usb: host: ehci-tegra: fix PHY error handling

[Felipe Balbi <balbi-l0cyMroinI0@public.gmane.org>]

PHY layer no longer returns NULL, we must
switch from IS_ERR_OR_NULL() to IS_ERR().

Hi Stephen,

I'm waiting for your topic branch before I can merge
this into my 'next' branch.

cheers
