ARM: msm: avoid calling debug_ll_addr on !MMU
MSM7X00A has an open-coded version of debug_ll_io_init so it
can use MT_DEVICE_NONSHARED as required by the platform.
However, this fails to build on no-MMU kernels because the
debug_ll_addr function is not available. Since the iotable_init
function doesn't actually do anyting in this configuration,
we can simply get away by enclosing the broken function call
in an #ifdef, which seems to be the least ugly workaround.
