The 8390 driver was structured by Al Viro to allow the flexibility
required by platforms.  lib8390.c contains the core code which drivers
explicitly include:
- 8390.c includes lib8390.c to provide the standard ISA based driver.
- etherh.c includes it with the accessors defined for RiscPC platforms,
  where it is addressed via the MMIO accessors with a device dependent
  register spacing.

Other platform drivers do something similar.

However, b9a9b4b0 caused the kernel to contain not only the etherh
private build of lib8390 (included in etherh.c) but also lib8390.c
itself, and referred the new net_device_ops methods to the ISA version.
The result of this is is not pretty:

Fix up b9a9b4b0 by making etherh's net_device_ops refer to the internal
lib8390 functions, and remove the build of the ISA 8390.c driver.
