dma-debug: fix displaying of dma allocation type

Browse source 
The commit 2e05ea5cdc ("dma-mapping: implement dma_map_single_attrs using
dma_map_page_attrs") removed "dma_debug_page" enum, but missed to update
type2name string table. This causes incorrect displaying of dma allocation
type.
Fix it by removing "page" string from type2name string table and switch to
use named initializers.

Before (dma_alloc_coherent()):
k3-ringacc 4b800000.ringacc: scather-gather idx 2208 P=d1140000 N=d114 D=d1140000 L=40 DMA_BIDIRECTIONAL dma map error check not applicable
k3-ringacc 4b800000.ringacc: scather-gather idx 2216 P=d1150000 N=d115 D=d1150000 L=40 DMA_BIDIRECTIONAL dma map error check not applicable

After:
k3-ringacc 4b800000.ringacc: coherent idx 2208 P=d1140000 N=d114 D=d1140000 L=40 DMA_BIDIRECTIONAL dma map error check not applicable
k3-ringacc 4b800000.ringacc: coherent idx 2216 P=d1150000 N=d115 D=d1150000 L=40 DMA_BIDIRECTIONAL dma map error check not applicable
