powerpc/kvm/cma: Improve kernel log during boot 



Current kernel gives:

[    0.000000] cma: Reserved 26224 MiB at 0x0000007959000000
[    0.000000] hugetlb_cma: reserve 65536 MiB, up to 16384 MiB per node
[    0.000000] cma: Reserved 16384 MiB at 0x0000001800000000

With the fix

[    0.000000] kvm_cma_reserve: reserving 26214 MiB for global area
[    0.000000] cma: Reserved 26224 MiB at 0x0000007959000000
[    0.000000] hugetlb_cma: reserve 65536 MiB, up to 16384 MiB per node
[    0.000000] cma: Reserved 16384 MiB at 0x0000001800000000
