Mis-use of BUS_PASS_ORDER_MIDDLE

[Howard Su]

I noticed several places there are code like this, especially in some arm
low level drivers.
EARLY_DRIVER_MODULE(aw_ccu, simplebus, aw_ccu_driver, aw_ccu_devclass,
    0, 0, BUS_PASS_BUS + BUS_PASS_ORDER_MIDDLE);

​I feel the usage of BUS_PASS_ORDER_MIDDLE is misused. There are another
macro EARLY_DRIVER_MODULE_ORDERED, which take an additional parameter
"order". I believe BUS_PASS_ORDER_xxx is used for that parameter.
