FIX: arm64: dts: hi3660: enable gpio_hubv2 by default for usb

This patch fixes the problem of when using UEFI, USB host doesn't work.

This patch removes gpio_hubv1. gpio_hubv1 is only useful to revision 1
(v1) of hikey960. But revision 1 is experimental, and is not available in
the market any more.

This patch enables gpio_hubv2 by default by deleting status = "disabled".
gpio_hubv2 is used by USB host/client switching. Corresponding driver code
is in drivers/misc/microchip/hub/hub_usb5734.c

Previously, HiSilicon bootloader reads board's id. According boardid
(v1 or v2), it modifies DTB node. Eg. when it reads a v2 board, it changes
node gpio_hubv2 status to: status = "ok".

But when we use UEFI, UEFI doesn't do the boardid detection, and it doesn't
change DTB. So, without this patch, both gpio_hubv2 and gpio_hubv1 are
"disabled", and switching from USB OTG to host always fails.
