etherh: Get working again.
Further to a71558d, this is round five of fixes to make etherh work
again. As mainline kernels stand, the fixes in b9a9b4b were the wrong
approach.
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, b9a9b4b 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:
Unable to handle kernel paging request at virtual address 12032030

Fix up b9a9b4b by making etherh's net_device_ops refer to the internal
lib8390 functions, and remove the build of the ISA 8390.c driver.
