dma-debug: Use %pa to format phys_addr_t

On 32-bit without LPAE:

    kernel/dma/debug.c: In function ‘debug_dma_dump_mappings’:
    kernel/dma/debug.c:537:7: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 9 has type ‘phys_addr_t’ {aka ‘unsigned int’} [-Wformat=]
    kernel/dma/debug.c: In function ‘dump_show’:
    kernel/dma/debug.c:568:59: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 11 has type ‘phys_addr_t’ {aka ‘unsigned int’} [-Wformat=]
