[PATCH] scsi: ufs: host: mediatek: require CONFIG_PM

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

The added print statement from a recent fix causes the
driver to fail building when CONFIG_PM is disabled:

drivers/ufs/host/ufs-mediatek.c: In function 'ufs_mtk_resume':
drivers/ufs/host/ufs-mediatek.c:1890:40: error: 'struct dev_pm_info' has no member named 'request'
 1890 |                         hba->dev->power.request,

It seems unlikely that the driver can work at all without
CONFIG_PM, so just add a dependency and remove the existing
ifdef checks, rather than adding another ifdef.

Fixes: 15ef3f5aa822 ("scsi: ufs: host: mediatek: Enhance recovery on resume failure")
