core: change the pattern used to generate asm-defines.h

This commit prepares support for the Clang compiler.

$O/core/include/generated/asm-defines.h is generated from
core/arch/arm/kernel/asm-defines.c by the C compiler with the -S flag
(generate assembler code), followed by some light post-processing with
sed.

The intermediate file ($O/core/include/generated/.asm-defines.s) is
actually not a valid assembler file. It contains illegal tokens, which
where chosen to make it easy to parse with sed. For example:

==>SM_CTX_SIZE #256 sizeof(struct sm_ctx) @

...is turned into:

#define SM_CTX_SIZE 256 /* sizeof(struct sm_ctx) */

While this works fine with GCC, the Clang compiler won't accept to
output invalid assembler. This commit slightly modifies the inline
assembler so that the needed information is contained within a .ascii
directive:

.ascii "==>SM_CTX_SIZE 248 sizeof(struct sm_ctx)" @

The 'c' constraint (%c0) is added to avoid the # prefix before an
immediate value, which is not accepted by Clang either.

build: introduce asm-defines-y

The Makefile rules that are used to generate a C header file containing
constants for struct offsets etc. are currently in mk/compile.mk. They
are used by core.mk which sets a variable (asm-defines-file) before it
includes compile.mk. This works well for this purpose, but does not
scale to several files.

There is a use case for platform code to be able to use the asm-defines
mechanism, too. Therefore, introduce a variable that can be used in any
sub.mk: asm-defines-y.

In addition, to avoid duplication, the DEFINE and DEFINES macros are
moved to their own header (core/include/gen-asm-defines.h), with the
added benefit that it can be explicitly excluded from the checkpatch
list and thus not generate any warning on the 'DEFINE' macro needing
parentheses.
