[PATCH] x86/asm: Use asm_inline() instead of asm() in amd_clear_divider()

[Uros Bizjak <ubizjak@gmail.com>]

Use asm_inline() to instruct the compiler that the size of asm()
is the minimum size of one instruction, ignoring how many instructions
the compiler thinks it is. ALTERNATIVE macro that expands to several
pseudo directives causes instruction length estimate to count
more than 20 instructions.

bloat-o-meter reports no code size changes.
