Subject: serial: 8250_bcm2835aux: Restore clock error handling

From: Stefan Wahren <wahrenst@xxxxxxx>

commit 83e571f054cd742eb9a46d46ef05193904adf53f upstream.

The commit fcc446c8aa63 ("serial: 8250_bcm2835aux: Add ACPI support")
dropped the error handling for clock acquiring. But even an optional
clock needs this.
