scsi: ufs: core: SCSI_UFS_HWMON depends on HWMON=y

When building an allmodconfig kernel, the following build error shows up:

aarch64-linux-gnu-ld: drivers/scsi/ufs/ufs-hwmon.o: in function `ufs_hwmon_probe':
/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:177: undefined reference to `hwmon_device_register_with_info'

Since SCSI_UFS_HWMON can't be built as a module, SCSI_UFS_HWMON has to
depend on HWMON=y.

          This provides support for UFS hardware monitoring. If enabled,
          a hardware monitoring device will be created for the UFS device.
