USB: EHCI: remove unused Link Power Management code
This patch (as1622) removes the USB-2.1 Link Power Management code
from the ehci-hcd driver. This code was never integrated with
usbcore, it is full of bugs, and it was not getting used by anybody.
However, the debugging code for dumping the LPM-related fields in the
EHCI registers is left in place. In theory it might be useful to see
these values, even though we don't use them.
This essentially amounts to a partial revert of commit
aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1
addendum: preparation) and an almost full revert of commit
48f24970144479c29b8cee6d2e1dbedf6dcf9cfb (USB: EHCI: EHCI 1.1
addendum: Basic LPM feature support) plus its follow-ons.
