The current eepro100 driver accesses its memory mapped registers directly
instead of using the standard I/O accessors. This can cause problems on
some systems as the accesses can get out of order. So convert the direct
volatile dereferences to use the normal in/out macros.

This function zeroes-out all the descriptors in the TX ring,
use memset() instead.

This code is replicated in the driver thrice almost verbatim, factor
it out into a separate function and clean it up. No functional change.

Add cache invalidation and flushes wherever the DMA descriptors are
written or read, otherwise this driver cannot work reliably on any
systems where caches are enabled.

Remove all the remaining use of the 'volatile' keyword, as this is
no longer required. All the accesses which might have needed this
use of 'volatile' have been repaired properly.

Move the functions around in the driver to prepare it for DM conversion.
Drop forward declarations which are not necessary anymore. No functional
change.

Use this macro to fully fill the PCI device ID table. This is mandatory
for the DM PCI support, which checks all the fields.

Pull the MII registration code into a separate function. Moreover,
properly free memory in case any of the registration or allocation
functions fail, so this fixes an existing memleak.

Those macros depended on specific variable names to be declared
at their usage sites, fix this by adding an argument to those

Drop the inline keyword from the static functions, the compiler has a
much better overview and can decide how to inline those functions much
better.

This is a trick in preparation for adding DM support. By passing in
the PCI BDF into the bus_to_phys()/phys_to_bus() macros and calling
that dev, we can substitute dev with udevice when DM support lands
and do minor adjustment to the macros to support both DM and non-DM
operation. No functional change.

Instead of doing ethernet device lookup by name every time there
is an MDIO access, pass the driver private data via mdiobus priv
to the MDIO bus accessors.

The RX/TX DMA descriptor rings are per-device-instance private data,
so move them into the private data.

Split the common code from the non-DM code, so it can be reused by

into the actual receiving part and free_pkt part to fit with the
DM.
