arm: rmobile: Add HopeRun HiHope RZ/G2N board support

The HiHope RZ/G2N board from HopeRun consists of main board
(HopeRun HiHope RZ/G2N main board) and sub board(HopeRun
HiHope RZ/G2N sub board). The HiHope RZ/G2N sub board sits
below the HiHope RZ/G2N main board.

This patch adds the required board support to boot HopeRun HiHope
RZ/G2N board.
