8390: Move the 8390 related drivers

Moves the drivers for the National Semi-conductor 8390 chipset into
drivers/net/ethernet/8390/ and the necessary Kconfig and Makefile
changes.

-   The HP EtherTwist chip implementation is a fairly routine DP8390
-   implementation.  It allows both shared memory and programmed-I/O buffer
-   access, using a custom interface for both.  The programmed-I/O mode is
-   entirely implemented in the HP EtherTwist chip, bypassing the problem
-   ridden built-in 8390 facilities used on NE2000 designs.  The shared
-   memory mode is likewise special, with an offset register used to make
-   packets appear at the shared memory base.  Both modes use a base and bounds
-   page register to hide the Rx ring buffer wrap -- a packet that spans the
-   end of physical buffer memory appears continuous to the driver. (c.f. the
-   3c503 and Cabletron E2100)
-
-   A special note: the internal buffer of the board is only 8 bits wide.
-   This lays several nasty traps for the unaware:
-   - the 8390 must be programmed for byte-wide operations
-   - all I/O and memory operations must work on whole words (the access
-     latches are serially preloaded and have no byte-swapping ability).
-
-   This board is laid out in I/O space much like the earlier HP boards:
-   the first 16 locations are for the board registers, and the second 16 are
-   for the 8390.  The board is easy to identify, with both a dedicated 16 bit
-   ID register and a constant 0x530* value in the upper bits of the paging
-   register.
