Message:

usbdev: refactor polling

Until now, device polling had to be executed by calling one of four
proxy functions, which served as a syntax sugar and had no clear
distinction between each other (not to mention misleading names and high
number of arguments).

In this commit, the four mentioned functions are discarded in favor of
one main function, which was proxied by them either way. The number of
arguments have decreased in favor of named struct fields in the auto
polling config structure.

Drivers, which make use of polling, such as usbhid and usbhub were
updated to the latest API design.
