Remove gcc csky fork since it doesn't build with the latest compilers
(gcc 8, 10, 11 tested) [1].
Removing the csky gcc fork has become unavoidable since the
Buildroot Docker image used by the gitlab CI will switch soon to
Debian bullseye soon [2].
The csky support for csky807 and csky810 has been upstreamed in
gcc 10 [3] and csky860 will be supported by gcc 12 [4]. There is
no info about the csky610. Although the csky architecture is
supported since gcc 10, the support was not enabled in Buildroot.
