Re: [PATCH v2] powerpc/fsl-booke: declare tlbcam_index for use in c file

KVM on E500 platform currently utilize TLB1 entries without  
bothering host,
that is using unused TLB1 entries.

So, KVM needs to read tlbcam_index to know exactly
which TLB1 entry is unused by host.

Remove num_tlbcam_entries declare and read from SPRN_TLB1CFG in KVM  
instead.
