x86/asm: Make <asm/asm.h> valid on cross-builds as well
Stephen Rothwell reported that the objtool cross-build breaks on
non-x86 hosts:

x86/asm: Make <asm/asm.h> valid on cross-builds as well
Stephen Rothwell reported that the objtool cross-build breaks on
non-x86 hosts:
> tools/arch/x86/include/asm/asm.h:185:24: error: invalid register name for 'current_stack_pointer'
> 185 | register unsigned long current_stack_pointer asm(_ASM_SP);
> | ^~~~~~~~~~~~~~~~~~~~~
The PowerPC host obviously doesn't know much about x86 register names.
Protect the kernel-specific bits of <asm/asm.h>, so that it can be
included by tooling and cross-built.

x86/asm: Use _ASM_BYTES() in <asm/nops.h>
Use the new generalized _ASM_BYTES() macro from <asm/asm.h> instead of
the "home grown" _ASM_MK_NOP() in <asm/nops.h>.
Add <asm/asm.h> and update <asm/nops
