    xen/riscv: fix MMIO alignment check in imsic_init()
    
    The MMIO alignment check in imsic_init() incorrectly uses cpu as
    the index into mmios[]. The loop index should be used instead.
    Otherwise, the alignment check may be performed on the wrong MMIO
    address.
    
    Fix the index used in the alignment check and corresponding printk.
