Matt Redfearn da40055ecf MIPS: paravirt: Fix undefined reference to smp_bootstrap
commit 951c39cd3bc0aedf67fbd8fb4b9380287e6205d1 upstream.

If the paravirt machine is compiles without CONFIG_SMP, the following
linker error occurs

arch/mips/kernel/head.o: In function `kernel_entry':
(.ref.text+0x10): undefined reference to `smp_bootstrap'

due to the kernel entry macro always including SMP startup code.
Wrap this code in CONFIG_SMP to fix the error.
