    RISC-V: Remove RV64E conflict
    
    Since RV32E *and* RV64E are ratified, RV64E is no longer invalid.
    
    This commit removes a restriction that prevents making base ISA with
    reduced GPRs with XLEN > 32.
    
    bfd/ChangeLog:
    
            * elfxx-riscv.c (riscv_parse_check_conflicts): Remove RV64E
            conflict since the ratified 'E' base ISAs include RV64E.
    
    gas/ChangeLog:
    
            * testsuite/gas/riscv/march-fail-base-02.d: Removed.
            * testsuite/gas/riscv/march-fail-base-02.l: Removed.
