[PATCH 2/2] arm64: dts: allwinner: h6: Pine H64: Add SPI flash node

[Andre Przywara <andre.przywara-5wv7dgnIgG8@public.gmane.org>]

The Pine H64 board comes with SPI flash soldered on the board, connected
to the SPI0 pins (so it can also boot from there).

Add the required DT node to make the flash accessible from Linux.
