KVM: MIPS: Define KVM_ENTRYHI_ASID to cpu_asid_mask(&boot_cpu_data)
The code in decode_config4() of arch/mips/kernel/cpu-probe.c
asid_mask = MIPS_ENTRYHI_ASID;
if (config4 & MIPS_CONF4_AE)
asid_mask |= MIPS_ENTRYHI_ASIDX;
set_cpu_asid_mask(c, asid_mask);
set asid_mask to cpuinfo->asid_mask.
So in order to support variable ASID_MASK, KVM_ENTRYHI_ASID should also
be changed to cpu_asid_mask(&boot_cpu_data).
