====================
Introduce Mellanox Technologies Switch ASICs switchdev drivers

This patchset introduces Mellanox Technologies Switch driver infrastructure
and support for SwitchX-2 ASIC.

The driver is divided into 3 logical parts:
1) Bus - implements switch bus interface. Currently only PCI bus is
   implemented, but more buses will be added in the future. Namely I2C
   and SGMII.
   (patch #2)
2) Driver - implemements of ASIC-specific functions.
   Currently SwitchX-2 ASIC is supported, but a plan exists to introduce
   support for Spectrum ASIC in the near future.
   (patch #4)
3) Core - infrastructure that glues buses and drivers together.
   It implements register access logic (EMADs) and takes care of RX traps
   and events.
   (patch #1 and #3)
