Subject: [PATCH 1/2] arm64: dts: rockchip: add spi controller aliases on rk3399

From: Quentin Schulz <quentin.schulz@...obroma-systems.com>

There are 6 SPI controllers on RK3399 and they are all numbered in the
TRM, so let's add the appropriate aliases to the main DTSI so that any
RK3399-based board doesn't need to define the aliases themselves to
benefit from stable SPI indices in userspace.
