arch/tile: complete migration to new kmap_atomic scheme

Browse Source 
This change makes KM_TYPE_NR independent of the actual deprecated
list of km_type values, which are no longer used in tile code anywhere.
For now we leave it set to 8, allowing that many nested mappings,
and thus reserving 32MB of address space.

A few remaining places using KM_* values were cleaned up as well.
