hwmon: (w83627hf) Add support for suspend
On suspend some register values are lost, most notably the Value RAM
areas but also other limits. Restore them on resume. On top of that,
some fixups are needed to work around BIOS bugs, in particular when
the BIOS omits running the same initialization sequence on resume
that it does after boot. In that case we have to carry initialization
over suspend.

WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x32/0x34()
Problem is that in __ieee80211_susped() we remove sdata (i.e wlan0
interface) and then during resume we call usb_unbind_interface() ->
ieee80211_unregister_hw() with sdata removed.
Patch fixes problem by adding .reset_resume calback, hence we do not
unbind usb device on resume. This callback can be the same as normal
.resume callback, sice we do all needed initalization during interface
start, which is performed on resume [ ieee80211_resume() ->
ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].
