Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Thanks to Okash's latest work, the TODO list is essentially empty, so
the way out from staging now seems open.
The status of the remaining issue mentioned in TODO is not clear, we
asked the speakup user mailing list for reproducer cases, but didn't get
a really specific scenario. One serious bug was fixed by 9d32c0cde4
("staging/speakup: fix get_word non-space look-ahead"), which does not
seem to really be related to the bug mentioned in TODO. Possibly the bug
mentioned in TODO has been fixed long ago and people have been thinking
that it was not because they can not distinguish the symptoms mentioned
in TODO from the symptoms of the bug fixed by 9d32c0cde4.

rtw_aes_decrypt, rtw_tkip_decrypt, rtw_wep_decrypt, rtw_aes_encrypt,
rtw_tkip_encrypt, rtw_wep_encrypt are takes (u8 *) second argiment and
always uses it as (struct recv_frame *) or (struct xmit_frame *).
This is causes a lot of unnecessary type casts
and complicates refactoring.
