This is a RFC for a series of patches I've been sitting on a while,
it applies on top of latest linus-git (#3-#9 need to be applied
in sequence).

These two are older; they've been updated a bit:

#1  improves stability of DB1200 board,
#2  is a buildfix for mtx-1 with gpiolib=n; the gpio api has
    been updated with new functions, which this patch adds.

the other patches mainly replace au_readl/au_writel with __raw_*
functions, and try to reduce the register address clutter in
the au1000.h header.  This was basically a single large patch
broken down into smaller ones, one for each ip block.

#3  removes most of the irq-controller related register defines
    and updates irq.c to get rid of au_readl/writel.
#4  converts IRQ PM to syscore_ops
#5  converts DBDMA PM to syscore_ops
#6  rewrite UART setup to use runtime CPU detection, and get
    rid of most of the uart base address defines
#7  rewrite ethernet setup to use runtime CPU detection,
    and get rid of most of the redundant ethernet constants
#8  updates the old au1000 dma driver: according to the
    databooks physical addresses should be used for source
    and destination; this also allows then to remove
    another bunch of redundant address constants.
#9  changes the GPIO1/GPIO2 defines into offsets from their
    respective ip block base.  I also had to fixup the
    mtx-1 wdt driver a bit since it modified the gpio2 block

All patches have been compile tested, and except for #7, #8 and
the wdt parts of #9 also been run- and PM-tested on the DB1200.

CCing Florian and Wolfgang: If you have time, please test #7-#9
on your MTX-1 and GPR boards!  I'd like to know whether ethernet
and the mtx-1 watchdog still work!  Thanks!

Please test/comment!

Thank you,
     Manuel Lauss
