fdf6cbe54d net: pcnet: Pass private data through dev->priv
Get rid of the global point to private data, and rather pass it
thought dev->priv. Also remove the unnecessary check for lp being
non-NULL, since it is always NULL at this point.

60074d9d3e net: pcnet: Wrap devbusfn into private data
Instead of using eth_device priv for this PCI devbusfn, free it
so it could be used for driver private data, and wrap devbusfn
into those driver private data.

Note that using the name dev for the variable is a trick left for
later, when DM support is in place, so dm_pci_virt_to_mem() can be
used with minimal ifdeffery.

246d2bfcf2 net: pcnet: Move private data allocation to initialize
The private data allocation does not have to be done every time the
NIC is initialized at run time, move the allocation to initialize
function, which means it will be done only once when the driver

1c38c36eb9 net: pcnet: Simplify private data allocation
The current code is horribly complex. Both the RX and TX buffer
descriptors are 16 bytes in size, the init block is 32 bytes in
size, so simplify the code such that the entire private data of
the driver are allocated cache aligned and the RX and TX buffer
descriptors are part of the private data.

This removes multiple malloc calls and cache flushes.
