Make fakehard device claim all 2.4 Ghz channels from 802.15.4-2006,
802.15.4a-2007 as supported by the hw.

Some of ieee802154 operations really shouldn't change passed net_device.

Follow the usual pattern of devices registration by adding new function
(wpan_phy_set_dev) that sets child->parent relationship and removing
parent argument from wpan_phy_register call.

IEEE 802.15.4-2006 defines channel pages that hold channels (max 32 pages,
27 channels per page). Allow the driver to specify supported channels
on pages, other than the first one.

In a couple of cases collapse some extra code like:
   int retval = NETDEV_TX_OK;
   ...
   return retval;
into
   return NETDEV_TX_OK;

IEEE 802.15.4-2006 adds new concept: channel pages, which can contain several
channels. Add support for channel pages in the API and in the fakehard driver.

This adds some perfunctory documentation comments to the IEEE 802.15.4
fakehard.c driver (Fake hard MAC) and the nl802154.h (outgoing netlink messages)
header.

These comments are not necessarily complete, but they do reference the
IEEE 802.15.4-2006 document where possible.

This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

menuconfig IEEE802154_DRIVERS is a bool that depends on tristate IEEE802154.
If the IEEE802154 symbol is 'm', the bool becomes 'y'.
This allows tristate symbols under IEEE802154_DRIVERS to be configured as
'y' and cause build problems.
Changing the menuconfig bool to a tristate fixes this.
