Aneesh Kumar K.V 6be3601517 powerpc/book3s64/radix: add debug message to give more details of vmemmap allocation 
Add some extra vmemmap pr_debug message that will indicate the type of
vmemmap allocations.

For ex: with DAX vmemmap optimization we can find the below details:
[  187.166580] radix-mmu: PAGE_SIZE vmemmap mapping
[  187.166587] radix-mmu: PAGE_SIZE vmemmap mapping
[  187.166591] radix-mmu: Tail page reuse vmemmap mapping
[  187.166594] radix-mmu: Tail page reuse vmemmap mapping
[  187.166598] radix-mmu: Tail page reuse vmemmap mapping
[  187.166601] radix-mmu: Tail page reuse vmemmap mapping
[  187.166604] radix-mmu: Tail page reuse vmemmap mapping
[  187.166608] radix-mmu: Tail page reuse vmemmap mapping
[  187.166611] radix-mmu: Tail page reuse vmemmap mapping
[  187.166614] radix-mmu: Tail page reuse vmemmap mapping
[  187.166617] radix-mmu: Tail page reuse vmemmap mapping
[  187.166620] radix-mmu: Tail page reuse vmemmap mapping
[  187.166623] radix-mmu: Tail page reuse vmemmap mapping
[  187.166626] radix-mmu: Tail page reuse vmemmap mapping
[  187.166629] radix-mmu: Tail page reuse vmemmap mapping
[  187.166632] radix-mmu: Tail page reuse vmemmap mapping

And without vmemmap optimization
[  293.549931] radix-mmu: PMD_SIZE vmemmap mapping
[  293.549984] radix-mmu: PMD_SIZE vmemmap mapping
[  293.550032] radix-mmu: PMD_SIZE vmemmap mapping
[  293.550076] radix-mmu: PMD_SIZE vmemmap mapping
[  293.550117] radix-mmu: PMD_SIZE vmemmap mapping
