scsi: ufs: exynos: Fix hibern8 notify callbacks

Browse Source 
v1 of the patch which introduced the ufshcd_vops_hibern8_notify()
callback used a bool instead of an enum. In v2 this was updated to an
enum based on the review feedback in [1].

ufs-exynos hibernate calls have always been broken upstream as it
follows the v1 bool implementation.
