[patch 7/8] RFC: configs/pinebook-pro-rk3399_defconfig: enable SYS_USB_EVENT_POLL_VIA_INT_QUEUE

[Arnaud Patard (Rtp)]

The default configuration will use SYS_USB_EVENT_POLL for handling the
usb keyboard and it makes the system really slow (eg slow keypress, 
loading kernel/initrd from grub-efi is taking ages).

Using CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE seems to be improving
things a lot, so use it.
