SPI support for CE4100, v2

[Sebastian Andrzej Siewior]

The SPI core inside CE4100 is very much the same as in PXA25x.
I Cc the ARM folks because patch 4 reorganizes some files so that they
can be access from x86. Yes, CE4100 is a x86 SoC :)
The SPI device is behind a PCI bus. The PCI probe code simply creates a
platform device so we don't have much changes to the platform driver.
There is no clock framework on x86 and the peripherals don't support
changing their clocks or to enable/disable them. So I provided dummy
function which keep the driver happy.

History:
v1: initial post
v2: - the patch touching subys_inticall() got removed.
    - platform_driver_probe() is replaced with platform_driver_register()
    - there are no files created in include/asm.

The patch series has been created with the -M option so file moves can
be easily noticed. The whole series is also available at
