powerpc/mm: Print kernel map details to dmesg

Browse source

This helps in debugging. We can look at the dmesg to find out
different kernel mapping details.

On 4K config this shows

 kernel vmalloc start   = 0xc000100000000000
 kernel IO start        = 0xc000200000000000
 kernel vmemmap start   = 0xc000300000000000

On 64K config:

 kernel vmalloc start   = 0xc008000000000000
 kernel IO start        = 0xc00a000000000000
 kernel vmemmap start   = 0xc00c000000000000
