[PATCH] phy-sun4i-usb: select 'USB_COMMON'

[Arnd Bergmann]

In commit "usb: phy: add USB_SUPPORT dependency", I tried to
fix the dependency for this driver, but unfortunately I missed
that we need both USB_COMMON and USB_SUPPORT here, and we
can still get the same link error in the much rarer case
that USB_COMMON is a loadable module and the phy driver is
build-in:

drivers/phy/phy-sun4i-usb.o: In function `sun4i_usb_phy_probe':
phy-sun4i-usb.c:(.text.sun4i_usb_phy_probe+0x1a6): undefined reference to `of_usb_get_dr_mode_by_phy'

This adds the select, hopefully fixing it properly this time.

I see the original patch hasn't made it into linux-next
yet, so ideally just fold this patch into the first one.

Sorry for not getting it right the first time around.
