    lsefimmap: support persistent memory and other UEFI 2.5 features · c79c59f1

    This should accompany
    	76ce1de7 Translate UEFI persistent memory type
    
    1. Add a string for the EfiPersistentMemory type 14 that was
    added in UEFI 2.5.
    
    2. Decode the memory attributes that were added in UEFI 2.5:
    * NV (non-volatile)
    * MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
      with partial memory mirroring)
    * RO (read-only)
    
    3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
    values rather than misusing SI power-of-ten units (KB, MB, etc.)
    
    4. The lsmmap command only decodes memory ranges sizes up to GiB scale
    units.  Persistent memory ranges will reach into the TiB scale.
    Since 64-bit size field supports TiB, PiB, and EiB, decode all of
    them for completeness.
    
    5. In the lsefimmap command, rewrite the print statements to
    * avoid rounding
    * avoid a big nested if/else tree.
    
    For example: In the sixth entry below, the value of 309MB implies
    316416KB but is really reporting 316436KB.
    
    Widen the size column to 6 digits to accommodate typical cases.
    The worst case value would require 14 digits; if that happens,
    let the columns get out of sync.
