misc: Add drivers for Axxia MISC devices

commit 6eb51b6e from
https://github.com/axxia/linux-yocto.git

 v5.10/standard/axxia-dev/base.

This contains the drivers need to support the MISC devices on the
Intel AXXIA board:

axxia-fault: enabled with AXXIA_FAULT kernel option
  Add fault handlers for system aborts

axxia-mdio: enabled with AXXIA_MDIO kernel option
  Provide access to the Axxia MDIO bus.

axxia-mtc: enabled with AXXIA_MTC kernel option
  The Master Test Controller (MTC) is a test generator that is fully
  compliant with IEEE 1149.1 and can run JTAG test sequences on
  external devices.

axxia-ncr: enabled with AXXIA_NCR kernel option
  Provides access to the INTEL Axxia NCR bus.

axxia-oem: enabled with AXXIA_OEM kernel option
  OEM calls to the secure monitor for Axxia.
  Add the ability to control the ACTLR_EL3 and ACTLR_EL2 registers
  on Axxia using OEM calls to the secure monitor. As this driver
  now does more than just control DSP clusters, the name has been
  changed.

axxia-pei: enabled with AXXIA_PEI kernel option
  Set up the PEI controllers in Linux instead of the boot loader.

axxia-smmon: enabled with AXXIA_SMMON kernel option
  Monitor the system memory controllers for errors.

1. Change ncr.h in smmon.c to axxia-ncr.h to avoid building error.
2. s/ACP/AXXIA_NET since there is no ACP option.]
