[PATCH 1/2] ARM: sa1111: Remove legacy suspend/resume support

[Lars-Peter Clausen]

There are currently no sa1111 device drivers that implement suspend/resume
and this patch removes the bus specific legacy suspend and resume callbacks.
This will allow us to eventually remove struct bus_type legacy suspend and
resume support altogether.

sa1111 device drivers wanting to implement suspend and resume can use dev PM
ops which will work out of the box without further modifications necessary.
