sun4i_csi: Fixes kernel bug during camera init, v4l field must be set from camera driver response

Just a one line patch that fixes the camera initialization on the
tablets.  I realize the rest of the driver code from allwinner is ugly
as sin, I'll try and submit a style patch later.

sun4i-usb: allow USB1.1 devices on OTG USB 2.0 port

When OTG port is USB2.0 type, USB1.1 devices do not work:

Enabling .has_tt flag on HCD appears to fix or at least workaround the issue:

Not sure if this is correct or complete fix, as with .has_tt kernel log shows
some warnings. On the other hand, musb uses same flag.

Tested over linux-sunxi-3.4 (+ otg-usb-2.0 patch), compile tested on
linux-sunxi-3.0.
