This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.
This patch also fixes some of the asm/prom.h ordering issues. It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.
This removes it along with the following changes:
- 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
on 6xx which is what they want anyway.
- A new symbol, PPC_BOOK3S, is defined that represent compliance with
the "Server" variant of the architecture. This is set when either 6xx
or PPC64 is set and open the door for future BOOK3E 64-bit.
- 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
PPC64 && PPC_BOOK3S
- A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
used to control the use of prom_init.c

This commit adds the setup code for booting Linux on AmigaOne G3SE (G3
only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were
sold by Eyetech and are based on MAI Logic's Teron boards and its
Articia S northbridge.
The AmigaOne uses U-boot as firmware, which doesn't support a flattened
device tree yet. The northbridge has some design flaws, which makes it
necessary to use non cacheable memory for DMA operations
(CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag
for memory pages.
