While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a macro
that only gets defined by the Makefiles in the kernel. Defining
such a macro was necessary in the early days of the kernel, since GCC
only started providing __ASSEMBLER__ since version 3.0 in 2000 (see
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=f8f769ea4e69 ).
However, having two macros can be very confusing nowadays for the
developers when switching between userspace and kernelspace coding,
or when dealing with uapi headers that should use __ASSEMBLER__
instead. So let's now standardize on the __ASSEMBLER__ macro that is
provided by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with just one comment tweaked manually in
arch/mips/include/asm/cpu.h (that was missing some underscores).

Converted bridge code to a platform driver using the PCI generic driver
framework and use adding platform devices during xtalk scan. This allows
easier sharing bridge driver for other SGI platforms like IP30 (Octane) and
IP35 (Origin 3k, Fuel, Tezro).

[paul.burton@mips.com:
- Leave __phys_to_dma(), __dma_to_phys() & pcibus_to_node() in
arch/mips/pci/pci-ip27.c since the motivation for moving them
disappeared when the driver stopped being moved to drivers/pci.]

This is the first patch of two to clean up/update the Xtalk detection
code used by IP27 with some of the code used in the IP30 port.
This specific patch adds Xtalk widget manufacturer and widget device
numbers to arch/mips/include/asm/xtalk/widget.h

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.
