wlan - Sync dev/netif/ral from FreeBSD

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

- Add auto TX power and RX sensitivity calibration support. Add two sysctl
nodes to enable/disable them. Calibration is only done when NIC operates
as STA, since it does not make sense when the NIC operates in other mode.
By default, they are all disabled.
- Add sysctl node for TX power correction. TX power correction is disabled
by default. This could be used when TX power calibration should not be
performed, e.g. when NIC operates as AP

Enable TX power and RX sensitivity calibration and set TX power correction
to 8 (-4db) makes my EW-7608PG work well @48Mb and @54Mb when it is near AP
(-44dbm ~ -58dbm), @54Mb ~50 retries for ~1080 packets. Originally the NIC
requires at least one retry for every packets @48Mb.

TX power calibration needs further investigation. Calibrating TX power
based on RSSI may not work weel; integrate it into TX rate control may work
better.

Various limits and correction values are obtained from Ralink RT61 driver.

# TX power stepping for Auto-AGC capable NICs is not in place yet.
# RX sensitivity calibration for long distance is not in place yet.

Add hardware crypto support for 2x61 part of ral(4). This kind of hardware

Add hardware crypto support for 2x61 part of ral(4). This kind of hardware
can do hardware TKIP, TKIP MIC, WEP40/104 and CCMP.

Registers and global/pairwise key table layout are obtained from Ralink RT61
linux driver. Their driver does not use pairwise key table, but how to setup
pairwise key table and how to enable pairwise key slot are shown. BUT That's
still NOT enough to use pairwise key --- driver has to write 1 to SEC_CSR4 to
make the wheel whirl. It is mentioned in no place, and I had to figure it
out myself ;)

2x61 part has 64 pairwise key slots, only last 60 slots will be used currently.
It is mainly because the RX descriptor does not contain a field to indicate
in which key table the decryption key belongs.

- Define macro for the number of channels. Use it instead of the magic
number.
- Define maximum and default channel TX power.
- The EEPROM regions, which contain 5GHz and 2GHz channels' TX power, are
not contiguous. Add rt2661_read_txpower_config() to read them seperately.
- Lower channel's TX power is in the lower byte of the 16bits EEPROM value,
while upper channel's TX power is in the upper byte of the 16bits EEPROM
value.
- Channel's TX power should never exceed maximum channel TX power, if it is
set it to default channel TX power.
- Rename rt2661_read_eeprom() to rt2661_read_config(), since we already have
rt2661_eeprom_read().

EEPROM layout, EEPROM values' layout and various limit values are obtained
from Ralink RT61 Linux driver.

For RT2500:

- Due to the inter-dependency nature of DONE/(ENCRYPT|DECRYPT) intr, reap desc
rings twice if one of them comes. This change gives me ~17.6% TX performance
