====================
net: mvpp2: improve the interrupt usage

This series aims to improve the interrupts descriptions and usage in the
Marvell PPv2 driver.

- Before the series interrupts were named after their s/w usage,
  which in fact can be configured. The series rename all those
  interrupts and add a description of the ones left over.

- In PPv2 the interrupts are mapped to vectors. Those vectors were
  directly mapped to a given CPU, and per-cpu accesses were done. While
  this worked on our cases, the registers accesses mapped to the vectors
  are not actually linked to a given CPU. They instead are linked to
  what is called a "s/w thread". The series modify this so that the s/w
  threads are used instead of the CPU numbers, by adding an indirection.
  This means we now can have systems with more CPUs than s/w threads.

This is based on today's net-next, and was tested on various boards
using both versions of the PPv2 engine.

Two more patches will be coming, to update the device trees describing a
PPv2 engine. The patches are ready, but will go through a different
tree. I'll send them once this series will be accepted. This is not an
issue as the PPv2 driver keeps the dt bindings backward compatibility.
