Merge branch 'devlink-Add-configuration-parameters-support'

Moshe Shemesh says:

====================
Add configuration parameters support

Add configuration parameters setting through devlink.
Each device registers supported configuration parameters table.
Each parameter can be either generic or driver specific.
The user can retrieve data on these parameters by "devlink param show"
command and can set new value to a parameter by "devlink param set"
command.
The parameters can be set in different configuration modes:
  runtime - set while driver is running, no reset required.
  driverinit - applied while driver initializes, requires restart
               driver by devlink reload command.
  permanent - written to device's non-volatile memory, hard reset required.

The patches at the end of the patchset introduce few params that are using
the introduced infrastructure on mlx4 and bnxt.

Command examples and output:

pci/0000:81:00.0:
  name internal_error_reset type generic
    values:
      cmode runtime value true
      cmode driverinit value true
  name max_macs type generic
    values:
      cmode driverinit value 128
  name enable_64b_cqe_eqe type driver-specific
    values:
      cmode driverinit value true
  name enable_4k_uar type driver-specific
    values:
      cmode driverinit value false

pci/0000:81:00.0:
  name internal_error_reset type generic
    values:
      cmode runtime value false
      cmode driverinit value true
