driver: replace dev_request_mem_region with dev_request_mem_resource ...

dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.

And use it inside struct fb_info. This struct has the advantage
that the supported modes can be passed around in a single pointer.

driver: Attach info callback to device, not to driver ...

Since the info is device specific and not driver specific, attach
the callback to the device. This makes it possible to have a info
callback for a device which does not have a driver attached.

There are major differences in the clock tree of the S3C24xx family and the

avoid an ifdef hell. But also use generic function names to be able to
share drivers among the S3C family.
