Pali Rohár 3b44b3fdf2 arm: mvebu: Add support for programming LD0 and LD1 eFuse

This patch implements LD eFuse programming support. Armada 385 contains two
LD eFuse lines, each is 256 bit long with one additional lock bit. LD 0
line is mapped to U-Boot fuse bank 64 and LD 1 line to fuse bank 65. U-Boot
32-bit fuse words 0-8 are mapped to LD eFuse line bits 0-255. U-Boot fuse
word 9 is mapped to LD eFuse line lock bit.

So to program LD 1 General Purpose Data line, use U-Boot fuse command:

    => fuse prog -y 65 0 0x76543210
    => fuse prog -y 65 1 0xfedcba98
    => fuse prog -y 65 2 0x76543210
    => fuse prog -y 65 3 0xfedcba98
    => fuse prog -y 65 4 0x76543210
    => fuse prog -y 65 5 0xfedcba98
    => fuse prog -y 65 6 0x76543210
    => fuse prog -y 65 7 0xfedcba98
    => fuse prog -y 65 8 0x1
