This will allow reduce the number of driver and device to search on.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

This adds code to probe devices from a devicetree. Most helper
functions are directly imported from Linux.

Drivers need to get their driver data either from devicetree or the platform
information. It should matter for the driver where this data comes from, so
introduce a common function for it.

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.

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.

resource_size_t can be 32bit or 64bit depending on the architecture.
Add a define for it to be able to printf a resource_size_t correctly

Instead of directly accessing the struct member of struct param_d
use the provided getter function.

Currently all devices have an id meaning that all devicenames
end with a number. This patch adds a DEVICE_ID_SINGLE to make
it ppossible to register a device without an id assigned to
it.

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.

Files associated to a device showed up in a long list. Instead,
print them in seperate lines and also show offset/size information

Otherwise, when a non active device is unregistered, we call
list_del on an unitialized list which oopses.

as now all the drivers and board have been switch to resource whe can drop
map_base and size from device_d
