scsi: ufs: host: mediatek: Require CONFIG_PM

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.
