This was added because of some legacy reasons from OMAP SOCs but
after testing and verifying with the keystone hardware folks, the
dsb in keystone_cpu_smc() is not necessary.
So drop it.

Register r12 is caller-save, so no need preserve it keystone_cpu_smc().

Because of inline asm usage in platsmp.c, smc instruction
creates build failure for ARM V6+V7 build where as using instruction
encoding for smc breaks the thumb2 build.
So move the code snippet to separate asm file and mark
it with 'armv7-a$(plus_sec)' to avoid any build issues.
