platform driver: Drop check for resource conflicts ...

The check is wrong since it would have to check whether the
new iomem region overlaps with an existing region. Checking
for the base address only is not enough.
Currently this is not possible because every device conflicts
with the top iomem region which covers the whole address space.

This at least fixes the regression that devices whose memory region
begins at 0x0 can no longer be succesfully registered.

driver: rewrite dev_printf as a function ...

Printing device context normally should be "driver instance:",
but instead we printed the device name twice. This patch fixes
this and as a bonus makes the binary a bit smaller. Instead of
a '@' between driver and instance this function now prints a
whitespace which is a bit more like Linux.

ehci: Fix resource size ...

We now have a resource size for the ehci hccr register space. This
was assumed to be 0x40 in size. On OMAP though it is only 0x10 and
then the hccr resource conflicts with the hcor resource which results
in a non working ehci port on beagle and panda boards. This patch
adds a nonintrusive workaround, it limits the hccr resource to 0x10,
which then also works on OMAP.

Later we should drop the multiple resources for the ehci port and
make the resource as specified in the datasheets.

This is broken since:

resource: store 'end' instead of 'size' in struct resource ...

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

devices: unregister children when unregistering a device ...

We currently do not allow to unregister a device when it
has children. However, the return value is seldomly checked.
Also this breaks for hot pluggable devices like USB which we have
to unregister when they disappear. The best way to fix this is to
unregister our children and also the partitions on the unregistered
device.
We unregister the device first and then afterwards the children.
We do this because for example network devices have a miidev as
child which they unregister themselves. So we only have to
unregister the children which are not cleaned up by the drivers,
namely fs devices.
Also, unregister all partitions on a disappearing device.
