    arch/risc-v: fix idle stack assign order
    
    The bc022f8cd8 introduces a static way to calculate idle stack
    address for risc-v platform. However, it uses the reverse order
    to access idle stack, which breaks boards with smp configuration.
    
    Correct the idle stack order of g_cpux_idlestack.
    
    Fixes: bc022f8cd8 ("arch/risc-v: unify idle stack calculation")
