Marcin Bukat 9605950788 rk27xx: re-enable the UDC interrupt at every connect 
usb_drv_exit() masks the UDC interrupt in the interrupt controller at
every disconnect, but only usb_init_device(), once at boot, unmasked
it. After the first unplug the UDC raised no more interrupts: on the
next plug the charging icon showed - plug detection polls VBUS_STS -
but the host's reset and requests went unanswered, so the device never
enumerated and the USB screen never came up.

Unmask it in usb_drv_init(), which runs at every connect, so that it
pairs with the mask in usb_drv_exit(). The interrupt is now masked
while USB is off, at boot too; nothing needs it then.

Tested on a Samsung YP-CP3: it enumerates at every replug.
