Landon J. Fuller 1728aef23d bhnd(4): Implement NVRAM support required for PMU bring-up.
- Added a generic bhnd_nvram_parser API, with support for the TLV format
  used on WGT634U devices, the standard BCM NVRAM format used on most
  modern devices, and the "board text file" format used on some hardware
  to supply external NVRAM data at runtime (e.g. via an EFI variable).

- Extended the bhnd_bus_if and bhnd_nvram_if interfaces to support both
  string-based and primitive data type variable access, required for
  common behavior across both SPROM and NVRAM data sources.
- Extended the existing SPROM implementation to support the new
  string-based NVRAM APIs.

- Added an abstract bhnd_nvram driver, implementing the bhnd_nvram_if
  atop the bhnd_nvram_parser API.
- Added a CFE-based bhnd_nvram driver to provide read-only access to
  NVRAM data on MIPS SoCs, pending implementation of a flash-aware
  bhnd_nvram driver.
