[PATCH] mm/damon: trace: print address range in hex

Currently, the address ranges are displayed in decimal format in
tracepoints for DAMON, but hexadecimal format is easier to compare with
address ranges in /proc/<pid>/numa_maps.

Existing tools such as damo need to be able to handle changing the format
of address ranges, so display address ranges in hexadecimal with a "0x"
prefix.
