    [nvptx] Unbreak build, add PTX_ISA_SM70
    
    With the commit "[nvptx] Choose -mptx default based on -misa" I introduced a
    use of PTX_ISA_SM70, without adding it first.
    
    Add it, as well as the corresponding TARGET_SM70.
    
    Build for x86_64 with nvptx accelerator.
    
    gcc/ChangeLog:
    
    2022-02-08  Tom de Vries  <tdevries@suse.de>
    
            * config/nvptx/nvptx-opts.h (enum ptx_isa): Add PTX_ISA_SM70.
            * config/nvptx/nvptx.h (TARGET_SM70): Define.
