This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.

Before using the PHY framework instead of the USB PHY one, we need to
move the OTG state into another place, since it won't be available when
USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.

phy-tahvo introduced the following smatch warnings:
drivers/usb/phy/phy-tahvo.c:203 tahvo_usb_set_host() warn: variable dereferenced before check 'otg' (see line 199)
drivers/usb/phy/phy-tahvo.c:235 tahvo_usb_set_peripheral() warn: variable dereferenced before check 'otg' (see line 231)
Fix by deleting bogus NULL pointer checks. The USB framework will always
call us with a valid OTG pointer.

Add Tahvo USB transceiver driver.
Based on old code from linux-omap tree. The original driver was written
by Juha Yrjölä, Tony Lindgren, and Timo Teräs.
