Subject[PATCH] ARM: milbeaut: fix build with !CONFIG_HOTPLUG_CPU
Date
When HOTPLUG_CPU is disabled, some fields in the smp operations
are not available or needed:

arch/arm/mach-milbeaut/platsmp.c:90:3: error: field designator 'cpu_die' does not refer to any field in type
'struct smp_operations'
.cpu_die = m10v_cpu_die,
^
arch/arm/mach-milbeaut/platsmp.c:91:3: error: field designator 'cpu_kill' does not refer to any field in type
'struct smp_operations'
.cpu_kill = m10v_cpu_kill,
^

Hide them in an #ifdef like the other platforms do.

Fixes: 9fb29c734f9e ("ARM: milbeaut: Add basic support for Milbeaut m10v SoC")
