With CONFIG_AXP288=y and CONFIG_USB_COMMON=n there is the following link
error:

The above functions are defined in drivers/usb/common/roles.c, but the build
system only enters the common directory depending on CONFIG_USB_COMMON. Fix
this by selecting the USB_COMMON symbol.

Hi,
there is another solution for this problem: replace depends on USB_SUPPORT
with depends on USB, but since CONFIG_USB selects other symbols I went
with the minimal fix and select the USB_COMMON symbol.
