Subject: [PATCHv2] scsi: ufs: Kconfig: SCSI_UFS_HWMON depens 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'
/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:177:(.text+0x510): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `hwmon_device_register_with_info'

/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:195:(.text+0x5c8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `hwmon_device_unregister'
aarch64-linux-gnu-ld: drivers/scsi/ufs/ufs-hwmon.o: in function `ufs_hwmon_notify_event':
/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:206: undefined reference to `hwmon_notify_event'
/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:206:(.text+0x64c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `hwmon_notify_event'
aarch64-linux-gnu-ld: /home/anders/src/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:209: undefined reference to `hwmon_notify_event'
/kernel/next/drivers/scsi/ufs/ufs-hwmon.c:209:(.text+0x66c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `hwmon_notify_event'

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