The patch set beginning with commit:
"ARM: ux500: Apply a ste-* prefix onto snowball.dts"
thru commit:
"ARM: ux500: Remove u9540.dts as it's been replaced"
altered the names of the ux500 device tree files but forgot
to:

- Rename the ccu8540-pinctrl.dtsi file

- Update #include statements from files using these
  files, so the build broke.

- Update the Makefile for the device trees so the build
  broke.

Fix it up so we can build them all again.

Instead of evenly splitting the 512 MiB area between prefetchable and
non-prefetchable memory spaces, increase the prefetchable memory space
to 384 MiB while at the same time decreasing the non-prefetchable memory
space to 128 MiB. This is a more useful default as most PCIe devices
require more prefetchable than non-prefetchable memory.

Beaver's PCIe lane configuration most closely matches x2 x2 x2 rather
than x4 x1 x1, since clocks 0 and 2 are used, and lanes 0 and 5 are used,
and the only way those align is with a x2 x2 x2 configuration.

Also, disable root port 1; there's nothing connected to it. Root port 0
is the on-board PCIe Ethernet, and port 2 is the mini-PCIe slot.

  Along with that, a few slightly more minor things, such as a missing
  Kconfig option to enable handling of denorm exceptions when not
  running under a hypervisor (or userspace will randomly crash when
  hitting denorms with the vector unit), some nasty bugs in the new
