flashchips: Add W25Q256JW_DTR
W25Q256JW currently has two variants, the W25Q256JW with device
ID 0x6019 added in commit be4682d and the W25Q256JW_DTR (aka
W25Q256JW-IM) with device ID 0x8019 added by this patch.
Winbond W25Q256-series chips have a few device IDs:
0x4019: W25Q256FV
0x6019: W25Q256JW
0x7019: W25Q256JV
0x8019: W25Q256JW_DTR
Hence we need to be more specific with naming than usual to avoid a
false positive with wildcards.
