Another bunch of duplicated code is gone..

Since we now use former HSCX specific fields in common code, they
get moved out of bcs->hw.hscx and into bcs directly.

Again, receive message end / receive pool full are similar enough to
easily share common code.

Most drivers had ->read_fifo already, so we could call it from
common code, so just add read_fifo to the ones which were still
missing it and there we go.

Now that a lot of duplicated xmit code is shared, start on the receive
path: Share code which reads a fragment from the FIFO and merges it
into the currently received frame.

When separating out the duplicated xmit handling, we were lucky that
we could reuse BC_Send_Data for our purposes. Introduce a more
extensible "struct bc_l1_ops" instead, and initialize that in
the code that provides the functionality, not in the users.

Realize that *_empty_fifo() and *_fill_fifo() are always called
under the card lock, so no additional protection when reading/writing
fifos is needed.

Same thing which just happened to hscx_irq.c - Use the struct
bc_hw_ops instead of macros and inlining.

Each driver for HSCX based cards defined some hardware access macros
and #include'd hscx_irq.c. Instead, we now add the needed routines to
the corresponding bc_hw_ops and use regular function calls. It's a slight
bit less efficient, but shouldn't be noticable.

Using {isac,hscx}_{read,write} instead of the low-level
readreg/writereg simplifies the code a bit.

Preparing for un-inlining hscx_irq.c, we add operations needed
to access the B-Channel FIFO's, similar to what we already have
for the D-Channel.

Basically only a cosmetic patch, with much renaming and a little
rearranging of code.

Just a simple search and replace, switch to the more commonly
used "u8" type.

In many cases, readreg()/writereg() users can be simplified by
passing struct IsdnCardState instead of individual register
addresses.

The following patch fixes an oopsable (according to a few reports) bug
in the multiple open exclusion logic in my sound drivers and a driver
derived from my code.

* Get WOL settings from EEPROM
* Remove PHY WOL support as device downshofts from 1GbE to 10/100 during
  suspend, which causes a PHY event, which causes the system to wake up!
  The downshifting to 10/100 is to reduce power.
