ARM: 8370/1: hisi: fix hip04 build without HOTPLUG_CPU

The hip04 smp implementation provides the hotplug operations (cpu_die
and cpu_kill) unconditionally at the moment, which leads to a build
error when HOTPLUG_CPU is disabled:

mach-hisi/platmcpm.c:242:13: note: (near initialization for 'hip04_smp_ops')
mach-hisi/platmcpm.c:242:2: error: unknown field 'cpu_die' specified in initializer
mach-hisi/platmcpm.c:243:2: error: unknown field 'cpu_kill' specified in initializer

This uses an #ifdef to remove the code from the build when that
option is not set.

Fixes: 905cdf9dda5d ("ARM: hisi/hip04: remove the MCPM overhead")
