[PATCH] bus: simple-pm-bus: Add CONFIG_ARM_AMBA for amba compatible of_device_id

[Jisheng Zhang]

I'm trying to run linux on some platforms with small size memory, so
every byte matters. The of_device_id is 196 Bytes on 32bit platforms,
add CONFIG_ARM_AMBA macro around the amba bus' of_device_id so that it
is removed if amba bus isn't used.
