Merge branch 'Refactor-lan9303_xxx_packet_processing'

Egil Hjelmeland says:

====================
Refactor lan9303_xxx_packet_processing

This series is purely non functional.

It changes the lan9303_enable_packet_processing,
lan9303_disable_packet_processing() to pass port number (0,1,2) as
parameter instead of port offset. This aligns them with
other functions in the module, and makes it possible to simplify the code.

The lan9303_enable_packet_processing, lan9303_disable_packet_processing
functions operate on port. Therefore rename the functions to reflect that
as well.

Reviewer pointed out lan9303_get_ethtool_stats would be better off with
the use of a lan9303_read_switch_port(). So that was added to the series.

Changes v3 -> v4:
 - Whitespace adjustments.

Changes v2 -> v3:
 - Patch 1: Removed the change in lan9303_get_ethtool_stats
 - Added patch 4: rename lan9303_xxx_packet_processing
 - Added patch 5: refactor lan9303_get_ethtool_stats

Changes v1 -> v2:
 - introduced lan9303_write_switch_port() in first patch
 - inserted LAN9303_NUM_PORTS patch
 - Use LAN9303_NUM_PORTS in last patch. Plus whitespace change.
