[PATCH v2 09/15] xen/asm-generic: introduce generic header smp.h

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

<asm/smp.h> is expcted to be generic between Arm, PPC and RISC-V
there by it is moved to asm-generic.

Right now it is common only by PPC and RISC-V but during work on
support of the mentioned arhcs <asm/smp.h> is expected to be the
same.

Signed-off-by: Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>

Changes in V2:
        - drop #ifded ASSEMBLY as this header isn't expected to be included in 
asm files.
        - update the commit message.
