Subject: [PATCH] scsi: ufs-mediatek: add dependency for RESET_CONTROLLER

When RESET_CONTROLLER is not set, kconfig complains about missing
dependencies for RESET_TI_SYSCON, so add the missing dependency
just as is done above for SCSI_UFS_QCOM.

Silences this kconfig warning:

WARNING: unmet direct dependencies detected for RESET_TI_SYSCON
Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y]
Selected by [m]:
- SCSI_UFS_MEDIATEK [=m] && SCSI_UFSHCD [=y] && SCSI_UFSHCD_PLATFORM [=y] && ARCH_MEDIATEK [=y]

Fixes: de48898d0cb6 ("scsi: ufs-mediatek: Create reset control device_link")

Hmm ... is the above patch complete? Shouldn't a similar dependency be
added to the ufs-hisi and ufs-sprd drivers? See also the following git
grep output:

$ git grep -nH 'include.*linux/reset.h' */ufs
drivers/ufs/host/ufs-hisi.c:16:#include <linux/reset.h>
drivers/ufs/host/ufs-mediatek.c:21:#include <linux/reset.h>
drivers/ufs/host/ufs-qcom.h:9:#include <linux/reset.h>
drivers/ufs/host/ufs-sprd.c:14:#include <linux/reset.h>

Thanks,

Bart.
