[PATCH v2] ARM64: dts: sun50i: a64: Add spi flash node for sopine

[manu@freebsd.org (Emmanuel Vadot)]

The Sopine and Pine64-LTS have a winbond w25q128 spi flash on spi0.
Add a node for it.

Changes in v2:
 - Only use the compatible 'jedec,spi-nor' since the device answer to
 the jedec command 0x9F
