drivers: ufs: handle return values of ufs_hba_ops callbacks

The return values of ufshcd_ops_link_startup_notify(),
ufshcd_ops_hce_enable_notify(), ufshcd_ops_init(), and
ufshcd_device_reset() are currently ignored.

Check and propagate these return values properly and emit appropriate
error messages on error.

While at it, remove the ufshcd_device_reset() wrapper, which just call
ufshcd_device_reset().
