docs: driver-api: add a series of orphaned documents

There are lots of documents under Documentation/*.txt and a few other
orphan documents elsehwere that belong to the driver-API book.

Move them to their right place.

-Writing Device Drivers for Zorro Devices

-Introduction
-------------
-
-The Zorro bus is the bus used in the Amiga family of computers. Thanks to
-AutoConfig(tm), it's 100% Plug-and-Play.
-
-There are two types of Zorro buses, Zorro II and Zorro III:
-
-  - The Zorro II address space is 24-bit and lies within the first 16 MB of the
-    Amiga's address map.
-
-  - Zorro III is a 32-bit extension of Zorro II, which is backwards compatible
-    with Zorro II. The Zorro III address space lies outside the first 16 MB.
-
-
-Probing for Zorro Devices
--------------------------
-
-Zorro devices are found by calling ``zorro_find_device()``, which returns a
-pointer to the ``next`` Zorro device with the specified Zorro ID. A probe loop
-for the board with Zorro ID ``ZORRO_PROD_xxx`` looks like::
-
-    struct zorro_dev *z = NULL;
-
-    while ((z = zorro_find_device(ZORRO_PROD_xxx, z))) {
-        if (!zorro_request_region(z->resource.start+MY_START, MY_SIZE,
-                                  "My explanation"))
-        ...
-    }
-
-``ZORRO_WILDCARD`` acts as a wildcard and finds any Zorro device. If your driver
-supports different types of boards, you can use a construct like::
-
-    struct zorro_dev *z = NULL;
-
-    while ((z = zorro_find_device(ZORRO_WILDCARD, z))) {
-        if (z->id != ZORRO_PROD_xxx1 && z->id != ZORRO_PROD_xxx2 && ...)
-            continue;
-        if (!zorro_request_region(z->resource.start+MY_START, MY_SIZE,
-                                  "My explanation"))
-        ...
-    }
-
-
-Zorro Resources
----------------
-
-Before you can access a Zorro device's registers, you have to make sure it's
-not yet in use. This is done using the I/O memory space resource management
-functions::
-
-    request_mem_region()
-    release_mem_region()
-
-Shortcuts to claim the whole device's address space are provided as well::
-
-    zorro_request_device
-    zorro_release_device
-
-
-Accessing the Zorro Address Space
----------------------------------
-
-The address regions in the Zorro device resources are Zorro bus address
-regions. Due to the identity bus-physical address mapping on the Zorro bus,
-they are CPU physical addresses as well.
-
-The treatment of these regions depends on the type of Zorro space:
-
-  - Zorro II address space is always mapped and does not have to be mapped
-    explicitly using z_ioremap().
-    
-    Conversion from bus/physical Zorro II addresses to kernel virtual addresses
-    and vice versa is done using::
-
-        virt_addr = ZTWO_VADDR(bus_addr);
-        bus_addr = ZTWO_PADDR(virt_addr);
-
-  - Zorro III address space must be mapped explicitly using z_ioremap() first
-    before it can be accessed::
- 
-        virt_addr = z_ioremap(bus_addr, size);
-        ...
-        z_iounmap(virt_addr);
