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).

Generic code may need to perform certain operations when EVA is
enabled, for example, configure the segmentation registers during
boot. In order to avoid using more CONFIG_EVA ifdefs in the arch code,
such functions will be added in this header instead.
Initially this header contains a macro which will be used by generic
code later on during VPEs configuration on secondary cores.
All it does is to call the platform specific EVA init code in case
EVA is enabled.
