[PATCH] powerpc/52xx: Fix an invalid ASM expression ('addi' used instead of 'add')

[Christophe Leroy]

  AS      arch/powerpc/platforms/52xx/lite5200_sleep.o
arch/powerpc/platforms/52xx/lite5200_sleep.S: Assembler messages:
arch/powerpc/platforms/52xx/lite5200_sleep.S:184: Warning: invalid register 
expression

In the following code, 'addi' is wrong, has to be 'add'

        /* local udelay in sram is needed */
  udelay: /* r11 - tb_ticks_per_usec, r12 - usecs, overwrites r13 */
        mullw   r12, r12, r11
        mftb    r13     /* start */
        addi    r12, r13, r12 /* end */
