Kernel coding standard prefers static inline functions instead
of macros, so use them for register accessors. This is to prepare
for adding LER, Live Error Recovery, checks to those accessors.

Temporarily provide macros for calling the new static inline
accessors until all references are changed.

The ixgbe_down function can now prevent multiple executions by
doing test_and_set_bit on __IXGBE_DOWN. This did not work before
introduction of the __IXGBE_REMOVING bit, because of overloading
of __IXGBE_DOWN. Also add smp_mb__before_clear_bit call before
clearing the __IXGBE_DOWN bit.

Add a bit, __IXGBE_REMOVING, to indicate that the module is being
removed. The __IXGBE_DOWN bit had been overloaded for this purpose,
but that leads to trouble. A few places now check both __IXGBE_DOWN
and __IXGBE_REMOVE. Notably, setting either bit will prevent service
task execution.

atheros: modify statistics code

Following Ben Hutchings's advice on how to fill net_stats in alx [1],
this patch modifies the other atheros ethernet drivers
similarly. Minor whitespace/empty line changes in atl1c and atl1e to
make the code completely consistent between atl1c, atl1e, and alx.

I don't have this hardware, so these patches have only been
compile-tested.

v2 (changes only in atl1):
 - don't set soft_stats.rx_missed_errors (Ben)
 - add errors to soft_stats.{rx,tx}_packets (Ben)
 - add soft_stats.rx_dropped field and update soft_stats.rx_dropped
   instead of netdev->stats (overwritten) outside of the stats
   update function

Detail of the changes (v1):
* atl1/atl1c/atl1e
  - fix collisions computation
  - rx_dropped = rx_rrd_ov
  - rx_over_errors = 0
  - rx_missed_errors = 0
  - X_packets = X_ok + X_errors

* only atl1c/atl1e
  - add rx_rxf_ov to rx_errors
