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

[Liu Yu <yu.liu@freescale.com>]

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.

[v2]
Remove num_tlbcam_entries declare and read from SPRN_TLB1CFG in KVM instead.
