Hi,

As subject line, map the ID value 0xd0c to "neoverse-n1". This reflects the value used by the GCC support  https://gcc.gnu.org/git/?p=gcc.git;a=blobdiff;f=gcc/config/aarch64/aarch64-cores.def;h=b0c7d2f23ace1e3c3a89f4e3ab10c9ad08f56b22;hp=7c4bd52049e5ae33241acce37414da91abaa989c;hb=9ed6834deacecd0e0671793e1440aa728939b93f;hpb=229d576cde53ac4396583da3642ca969cca413d1

I've got no commit access over here, so would appreciate this being committed on my behalf if it is OK.

Thanks,
James
