Subject: [PATCH] MIPS: Fix build warning about "PTR_STR" redefined under CONFIG_TEST_PRINTF

Replace PTR_STR with INST_PTR_STR to fix the following build warning when
CONFIG_TEST_PRINTF is set:

CC lib/test_printf.o
lib/test_printf.c:214:0: warning: "PTR_STR" redefined
#define PTR_STR "ffff0123456789ab"
