From: Sui Jingfeng <suijingfeng@loongson.cn>

The io_state variable in the vga_arb_write() function is declared with
unsigned int type, while the vga_str_to_iostate() function takes 'int *'
type. To keep them consistent, this patch replaceis the third argument of
vga_str_to_iostate() function with 'unsigned int *' type.
