replaced snprintf usage in amdgpu_pm.c with sysfs_emit
 fixed warning on comparing int with uint32_t in amdgpu_get_pp_num_states()

== Test ==
AMDGPU_PCI_ADDR=`lspci -nn | grep "VGA\|Display" | cut -d " " -f 1`
AMDGPU_HWMON=`ls -la /sys/class/hwmon | grep $AMDGPU_PCI_ADDR | cut -d " " -f 10`
HWMON_DIR=/sys/class/hwmon/${AMDGPU_HWMON}

lspci -nn | grep "VGA\|Display"  > scnprintf.test.log
