Add the full description of the Hynix H27UBG8T2BTR-BC NAND chip in the
nand_ids table so that we can later use the NAND ECC infos and ONFI timings
mode in controller drivers.

Still hoping to get this series [1] merged in 4.8, but if that's
not the case, I'll apply your patch.

BTW, that would be great if you could test it on your platforms.

It seems that Hynix-specific initialization code can't handle H27UBG8T2BTR-BC
chip:

[    0.886153] nand: Could not find valid ONFI parameter page; aborting
[    0.892665] nand: device found, Manufacturer ID: 0xad, Chip ID: 0xd7
[    0.899025] nand: Hynix 1c03000.nand
[    0.902596] nand: bus width 8 instead 16 bit
[    0.906858] nand: No NAND device found
[    0.910620] sunxi_nand 1c03000.nand: failed to init nand chips
[    0.916528] sunxi_nand: probe of 1c03000.nand failed with error -22

Regards,

Boris
