[PATCH v2 4/5] roc-pc-plus-rk3399: Introduce new variant

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@nabladev.com>

The roc-pc-plus-rk3399 board shares a lot of features with the
existing supported roc-pc-rk3399 board.

Its devicetree is also supported in the upstream kernel.

The plus variant has only a 12V supply. It contains a XMC XM25QH128C
SPI NOR flash.

Add support for the plus variant.
