    gdb/riscv: Make some target description functions constant
    
    Makes more of the interface related to fetching target descriptions
    constant.
    
    gdb/ChangeLog:
    
    	* arch/riscv.h (riscv_create_target_description): Make return type
    	const.
    	* arch/riscv.c (riscv_create_target_description): Likewise.
    	* riscv-tdep.c (riscv_find_default_target_description): Likewise.
