Subject: [PATCH] ARM: msm: fix compilation flags for MSM_SCM (part 2)

eca55f4 (ARM: msm: fix compilation flags for MSM_SCM, 2011-11-08)
added the correct assembler directive for the first smc instance
but missed the second instance in scm_get_version(). Add it so we
can compile this file with newer binutils.
