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.
DTS files apart from r8a774b1-hihope-rzg2n-u-boot.dts and
r8a774b1-u-boot.dtsi have been imported from linux 5.9 commit
bbf5c979011a ("Linux 5.9")
This patch adds the required board support to boot HopeRun HiHope
RZ/G2N board.
