Implement reading NB and SB fuses of Armada 37xx SOC via U-Boot fuse API. Banks 0-43 are reserved for accessing Security OTP (not implemented yet). Bank 44 is used for accessing North Bridge OTP (69 bits via words 0-2). Bank 45 is used for accessing South Bridge OTP (97 bits via words 0-3). Write support is not implemented yet because it looks like that both North and South Bridge OTPs are already burned in factory with some data. The meaning of some bits of North Bridge is documented in WTMI source code. The meaning of bits in South Bridge is unknown.
