[PATCH 00/31] Clean up amba/primecell bus support

[Russell King - ARM Linux]

This patch set cleans up the AMBA/Primecell bus support.  Contained
within this set are:

1. Patches 1-5 - Allocation APIs
   It seems several places in the kernel want to allocate and register
   amba_device structures.  Let's make this official, and common code.
   So we introduce amba_device_alloc(), amba_device_add(), and
   amba_device_put() APIs, which provide the necessary support safely
   for this.

   Convert the DT, ux500, Integrator/AP and mxs code to use these APIs
   rather than their private version.

2. Patches 6-17 - NO_IRQ cleanup
   Making IRQ number 0 mean 'no irq' for the AMBA drivers and bus layer.
   We get rid of NO_IRQ initializers in this across various platforms,
   and make the bus layer warn if '-1' is passed in a device as an IRQ.
   This prevents new occurances of NO_IRQ initializers for this bus type
   going by unspotted.

3. Patches 18-31 - static initializers
   Provide a standardized set of initializers for statically declared
   AMBA devices.  We provide two - one for the simpler APB devices,
   and one for AHB devices.  The major difference between these two is
   the setting of the DMA mask - APB peripherals do not have DMA
   capability themselves.

While updating (3), I came across new additions in Spear3xx and the
Samsung directories which added AMBA devices, which are declared
globally.  The Spear3xx devices are used in other files, so that's
fine.

Samsung devices don't seem to be - and that needs fixing (did someone
not run checkpatch or sparse on these changes?)  Please send fixes.

Acks for these patches are welcome.
