Make the tx ints processing same as rx ones via napi.
The idea got from e1000. The interrupt disabling is
still not fine grained.

Replace occurrences of 'if (<bool expr> == <1|0>)' with
'if ([!]<bool expr>)'

Replace occurrences of '<bool var> = (<non-bool expr>) ? true : false'
with '<bool var> = <non-bool expr>'.

Replace occurrence of '<bool var> = <non-bool expr>' with
'<bool var> = !!<non-bool expr>'

While the latter replacement is not really necessary, it is done here for
consistency and clarity.  No functional changes.

- pci_resource_start() can be removed from sis900_get_mac_addr() because
  the IO range is maped and stored into the device private struct early
  in the device probe function.
- the driver contains a few direct accesses to low IO ports that forbid
  to re(#)define the usual out{l, w, b} macros.

The bulk of the patch comes from the __iomem changes.

- the phy read and write operations were carrying the chip id deep
  down the call chain. Let's waste a pointer and contain the flying
  spaghetti monster.
- phy_{read, write}_1bit only need to access the DCR9 register. The loss
  of generality here should not hurt.
- removed a leftover printk of the EISA era. This is a pure PCI device.
