wireless: move sequence number arithmetic to ieee80211.h

Move the sequence number arithmetic code from mac80211 to
ieee80211.h so others can use it. Also rename the functions
from _seq to _sn, they operate on the sequence number, not
the sequence_control field.

Also move macros to convert the sequence control to/from
the sequence number value from various drivers.

ieee80211: mark 802.11 related structs as being 2-byte aligned

Regardless of what header features they use, or if they align the IP
header or not, 802.11 packets from all drivers guarantee a 2-byte
alignment (and there's a debug WARN_ON in case they don't).

Annotate packet structs with __aligned(2) to allow the compiler to use
16-bit load/store operations on platforms with extremely inefficient
unaligned access (e.g. MIPS).

This reduces code size and improves performance on affected platforms
and causes no binary code change on others.

wireless: remove unused VHT MCS defines

There's an enum with the same values (but slightly
different names except for NOT_SUPPORTED) that is
actually used, so remove the defines.

mac80211: restrict peer's VHT capabilities to own

Implement restricting peer VHT capabilities to the device's own
capabilities. This is useful when a single driver supports more
than one device and the devices have different capabilities
(often they will differ in the number of spatial streams), but
in particular is also necessary for VHT capability overrides to
work correctly -- otherwise it'd be possible to e.g. advertise,
due to overrides, that TX-STBC is not supported, but then still
use it to TX to the AP because it supports RX-STBC.

carl9170 firmware: always reset usb endpoints

It isn't clear what the firmware is supposed to do
when it is initializing the usb phy. The spec says
something about clearing the STALLED/HALTED flags
however the original firmware doesn't do that?!

kconfig: add a function to get the CONFIG_ prefix

Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means
the CONFIG_ prefix is hard-coded at compile time. This goes against
having a run-time defined CONFIG_ prefix.

Add a function that returns the CONFIG_ prefix to use (but keep the
current hard-coded behavior, to be changed in a later patch).

To avoid touching all the code that uses the CONFIG_ macro, we just
undef it, and define it to be a call to the function.

kconfig: get CONFIG_ prefix from the environment

Currently, the CONFIG_ prefix is hard-coded in the kconfig frontends
executables. This means that two projects that use kconfig with
different prefixes can not share the same kconfig frontends.

Instead of hard-coding the prefix in the frontends, get it from the
environment, and revert back to hard-coded value if not found.

kbuild: Fix missing '\n' for NEW symbols in yes "" | make oldconfig >conf.new

According to Documentation/kbuild/kconfig.txt, the commands:

    yes "" | make oldconfig >conf.new
    grep "(NEW)" conf.new

should list the new config symbols with their default values.
However, currently there is no line break after each new symbol.  When
kconfig is interactive the user will type a new-line at this point,
but when non-interactive kconfig must print it.
