Stephen Rothwell 98245c169a [POWERPC] remove include of asm/of_device.h from pmi.h
pmi.h does not diectly reference anything in of_device.h and of the two
files that include asm/pmi.h, one includes of_device.h and the other
includes of_platform.h (which includes of_device.h).

Christian Krafft 813f90728e [CELL] pmi: remove support for mutiple devices.
The pmi driver got simplified by removing support for multiple devices.
As there is no more than one pmi device per maschine, there is no need to
specify the device for listening and sending messages.

This way the caller (cbe_cpufreq) doesn't need to scan the device tree.
When registering the handler on a board without a pmi
interface, pmi.c will just return -ENODEV.

The patch that fixed the breakage of cell_defconfig has been
broken out of the earlier version of this patch. So this is
the version that applies cleanly on top of it.

Christian Krafft 0e8266437c [POWERPC] Add PMI driver for cell blade
This adds driver code for the PMI device found in future IBM products.
PMI stands for "Platform Management Interrupt" and is a way to
communicate with the BMC (Baseboard Management Controller).
It provides bidirectional communication with a low latency.
