This patch allows the use of IRQ to notify the change of GPIO status
on MPC8xx CPM IO ports. This then allows to associate IRQs to GPIOs
in the Device Tree.
Ex:
CPM1_PIO_C: gpio-controller@960 {
#gpio-cells = <2>;
compatible = "fsl,cpm1-pario-bank-c";
reg = <0x960 0x10>;
fsl,cpm1-gpio-irq-mask = <0x0fff>;
interrupts = <1 2 6 9 10 11 14 15 23 24 26 31>;
interrupt-parent = <&CPM_PIC>;
gpio-controller;
};
The property 'fsl,cpm1-gpio-irq-mask' defines which of the 16 GPIOs
have the associated interrupts defined in the 'interrupts' property.

This saves runtime memory and fixes lots of sparse warnings like this:
CHECK arch/powerpc/sysdev/micropatch.c
arch/powerpc/sysdev/micropatch.c:27:6: warning: symbol 'patch_2000'
was not declared. Should it be static?
arch/powerpc/sysdev/micropatch.c:146:6: warning: symbol 'patch_2f00'
was not declared. Should it be static?

When cpm2.h included into spi_mpc8xxx driver, the SPI defines
in the header conflict with defines in the driver.
We don't need them in the header file, so remove them. Plus
remove "struct spi", we'll use a better version in the driver.

We no longer user IMAP_ADDR for anything so kill it off.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
