arm64: dts: allwinner: Use the new r_intc binding

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.

Update the device trees to use the new binding.

arm64: dts: allwinner: pine64: Prepare optional UART nodes with pinctrl

Pine64 exposes all A64 UARTs, not just UART0.

Since the pins can be used as GPIO, don't enable the new UART nodes by
default, but prepare the pinctrl settings to aid in activating them via
overlays, i.e., overriding the status property of &uartX nodes.

For UART4 (Euler) the safer route of not including RTS/CTS pins is chosen,
whereas for UART1 (Bluetooth) they are included.

Add the corresponding pinctrl nodes where missing.

always present, causing confusion on the user's part.

dtc cannot resolve an overlay's &uart2 reference for strings, only for
phandles, so it would need to hardcode the full node path.

Avoid this and enforce reliable numbering by adding serialX aliases for:

UART1 - on Wifi/BT connector
UART2 - on Pi-2 connector
UART3 - on Euler connector
UART4 - on Euler connector

The Pine64 is a cost-efficient development board based on the
Allwinner A64 SoC.
There are three models: the basic version with Fast Ethernet and
512 MB of DRAM (Pine64) and two Pine64+ versions, which both
feature Gigabit Ethernet and additional connectors for touchscreens
and a camera. Or as my son put it: "Those are smaller and these are
missing." ;-)
The two Pine64+ models just differ in the amount of DRAM
(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
patches the DT accordingly we just need to provide one DT for the
Pine64+.
