iwl3945: iwl3945_queue and iwl3945_channel_info replacement

This patch replaces the queue and channel info 3945 structures with the iwl
ones.

The initial goal was to replace the channel info structure. Once we do that,
and then include iwl-dev.h instead of iwl-3945.h, we still get build errors
due to several routines and macro redefinitions. This is why this patch also
includes:
- TFD39_MAX_PAYLOAD definition for 3945.
- CMD_SIZE, CMD_HUGE, CMD_SKB duplication removal.
- iwl3945_queue replacement in order to also get rid of the duplicated
get_cmd_index routine.

Getting rid of any of those needs the iwl-dev.h inclusion which then creates
build errors due to definitions duplication. This is why we include all those
in the same patch.

rt2x00: Introduce RXDONE_SIGNAL_MASK mask

Improve error message reporting when a frame was received
with unknown rate. Instead of using the boolean check if
the frame is supposed to be a PLCP value or not, we should
add a new mask (RXDONE_SIGNAL_MASK) which returns the type
identification for a signal value (i.e. PLCP). At the moment
we only have 2 different types, but more will arrive when
support for 11n is added.

rt2x00: Restrict interface between rt2x00link and drivers

Restrict drivers to only access link_qual structure during
link tuning. The contents of these fields are for the drivers
and all fields are allowed to be changed to values the driver
considers correct.

This means that some fields need to be moved outside of this
structure to restrict access only to rt2x00link itself.
This allows some code to be moved outside of the rt2x00.h header

at the start of the function. Because this is an
indirect register access has some costs attached
to it (especially for USB hardware).

We already store the value read from the register
into the vgc_level value inside the link structure.
Instead of reading from the register we can read that
field directly and base the tuner on that value.

This reduces the time the registers are locked with
the csr_mutex and speeds up the link_tuner processing.
