[PATCH 5/5] fc: FDMI enhancement

[Javed Hasan <jhasan@marvell.com>]

Added RHBA and RPA attributes type and length.
As par FC_GC_7 document section "Table 400 – Attribute Entry Types and associated Values"
ascii type attributes length can be vary from "4 to 256 byte".
If we keep all RHBA ascii attributes length 256 then total length is 
going upto 2750, which is far more than 2048 (max frame size).

In libfc we do have logic to split FCP commands but not for CT commands.
Practically all version/names get covered with in 64 bytes except OS 
name, for that we need 128 bytes.
Hence length of all RBHA ascii attributes length reduced to 64 bytes
and 128 bytes in case OS name.

RPA attributes total length is with in frame size.
