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

When MUSB is a loadable module, we get a link error for a built-in
CPCAP driver:
drivers/phy/built-in.o: In function `cpcap_usb_phy_remove':
phy-cpcap-usb.c:(.text+0xed9): undefined reference to `musb_mailbox'
This adds a Kconfig dependency to prevent this broken configuration,
enforcing that CPCAP can only be a module when MUSB is also a module.

Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a
multiplexing USB PHY.
This USB PHY can operate at least in four modes using pin multiplexing
and two control GPIOS:
- Pass through companion PHY for the SoC USB PHY
- ULPI PHY for the SoC
- Pass through USB for the modem
- UART debug console for the SoC
This patch adds support for droid 4 USB PHY and debug UART modes,
support for other modes can be added later on as needed.
Both peripheral and host mode are working for the USB. The
host mode depends on the cpcap-charger driver for VBUS.
VBUS and ID pin detection are done using cpcap-adc IIO ADC
driver.
