Patching UP/SMP alternatives inside inline assembly blocks is useful
outside of the spinlock implementation, where it is used for sev and wfe.
This patch lifts the macro into processor.h and gives it a scarier name
to (a) avoid conflicts in the global namespace and (b) to try and deter
its usage unless you "know what you're doing". The W macro for generating
wide instructions when targetting Thumb-2 is also made available under
the name WASM, to reduce the potential for conflicts with other headers.

BSYM macro is only needed for assembly files and its usage in c files is
wrong, so only define it for assembly.

This patch adds various C and assembler macros that help with using
the unified assembler syntax for compiling files to either ARM or
Thumb-2 modes.
