Subject: [PATCH] phy: cpcap-usb: Fix missing return statement

Commit 8ae904e3c236 ("phy: cpcap-usb: Add CPCAP PMIC USB support")
is missing return statement as noted by Colin Ian King
<colin.king@...onical.com>. If the optional pins are not configured,
we just want to return early and not attempt to configure the pins.
