Subject: [PATCH v2 0/2]  usb: phy: tegra: add support for HSIC mode

Add support for HSIC mode into phy driver. HSIC mode is supported by
second USB controller in Tegra SoC and is used for connecting modem.
Linux kernel has support for HSIC mode in the controller driver itself
(Chipidea driver) but USB PHY part was missing until now.

Tested on LG Optimus Vu smartphone with Infineon/Comneon modem on usb2
line.
