scsi: ufs: core: Rename ufshcd_auto_hibern8_enable() and make it static

Browse Source 
Rename ufshcd_auto_hibern8_enable() into ufshcd_configure_auto_hibern8()
since this function can enable or disable auto-hibernation. Since
ufshcd_auto_hibern8_enable() is only used inside the UFSHCI driver core,
declare it static. Additionally, move the definition of this function to
just before its first caller.
