    soc/imgtec/pistacchio: Implement hard_reset()
    
    Verified boot needs hard_reset() now, so offer a dummy implementation
    for the Imagination chip. Sorry, I don't have the specs for this chip
    anymore to make a real implementation, but I would like to keep this
    code from bit rotting.
