net: ieee802154: at86rf230: Forward Tx trac errors

Commit 493bc90a9683 ("at86rf230: add debugfs support") brought trac
support as part of a debugfs feature, in order to add some testing
capabilities involving ack handling.

As we want to collect trac errors but do not need the debugfs feature
anymore, let's partially revert this commit, keeping the Tx trac
handling part which still makes sense. This allows to always return the
trac error directly to the core with the recently introduced
ieee802154_xmit_error() helper.

treewide: replace '---help---' in Kconfig files with 'help'

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

ieee802154: hwsim: add replacement for fakelb

This patch adds a new virtual driver mac802154_hwsim which is based on
the fakelb driver.
The fakelb driver will get deprecated and hopefully removed someday.
The main reason for doing this step is to rename the driver to
mac802154_hwsim to have a similar naming scheme as mac80211_hwsim,
which is more popular in the 802.11 wireless word and the idea is the
same behind this driver.

The new features of this driver are to have knowledge about connected
edges, which can be changed during runtime. This offers a testing
environment for routing protocols e.g. RPL.
The default behaviour is still as fakelb: two radios connected to each
other. New added radios during runtime will not be connected to other
wpan_hwsim instances.

The netlink api is not namespace aware on purpose, only the registered
wpan_phy's can be moved to namespaces. The physical layer according to
wiresless "air" communication can be handled across namespaces.

Furthermore the edges can be weighted with the LQI value according IEEE
802.15.4 which offers additional handling to mark bad or good connection
indicators to other connected virtual phys.

ieee802154: Add CA8210 IEEE 802.15.4 device driver

Add driver source and config for softMAC implementation of Cascoda's CA8210
IEEE 802.15.4 transceiver device. The driver mimics a common PHY-only
implementation despite the CA8210 being a hardMAC device which exposes a SAP
interface to the fully integrated MAC.

The chip is a modem-only device with an integrated processor which runs the
802.15.4 MAC. The chip communicates via full-duplex SPI with additional pins
for NIRQ and NRESET. The chip can also output its 16MHz clock to a GPIO with a
configurable divider.

The driver can be configured to implement a debugfs node that provides access
to the SAP-based API to drive mechanisms not currently supported by the
standard kernel interface.

mrf24j40: add regmap support

This patch introduce regmap support for short and long address space of
mrf24j40. It's only possible to use regmap_read/write/update_bits for
long address range. This is because I added lowlevel bus operation
because the write operation need to set the 12th bit to mark a register
write, but regmap only supports to set bits for register write access in
the first byte. We use other regmap register functions than
read/write/update_bits, so this should be fine.

This patch adds support for the atusb transceiver.

The current driver supports basic functionality only. Possible further
tasks would be to sync functionality with the at86rf230 driver, because
the atusb use internally an at86rf231 transceiver. Some of these
features need a firmware update like AACK and ARET handling.
