Felipe Balbi 7009bdd7f3 usb: otg: move usb_otg_state_string to usb-common.c
otg.c only had a single function definition
which might make more sense to be placed in
usb-common.c. While doing that, we also delete
otg.c since it's now empty.

Felipe Balbi d1e3d757f7 usb: common: introduce usb_state_string()
this function will receive enum usb_device_state
and return a human-readable string from it or,
case an unknown value is passed as argument,
the string "UNKNOWN".

Michal Nazarewicz e538dfdae8 usb: Provide usb_speed_string() function
In a few places in the kernel, the code prints
a human-readable USB device speed (eg. "high speed").
This involves a switch statement sometimes wrapped
around in ({ ... }) block leading to code repetition.

To mitigate this issue, this commit introduces
usb_speed_string() function, which returns
a human-readable name of provided speed.

It also changes a few places switch was used to use
this new function.  This changes a bit the way the
speed is printed in few instances at the same time
standardising it.
