The compatible string "simple-bus" is well defined in ePAPR, while
I see no documentation for the "arm,amba-bus" arnywhere in ePAPR or
Documentation/devicetree/.
DT is also used by other projects than Linux kernel. It is not a
good idea to rely on such an unofficial binding.
This commit
- replaces "arm,amba-bus" with "simple-bus"
- drops "arm,amba-bus" where it is used along with "simple-bus"
