powerpc/52xx: Fix an invalid ASM expression ('addi' used instead of 'add')
[ Upstream commit 8a87a507714386efc39c3ae6fa24d4f79846b522 ]
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 */
