The EK874 development kit from Silicon Linux is made of CAT874 (the main
board) and CAT875 (the sub board that goes on top of CAT874).
This patch adds the required board support to boot Si-Linux EK874 board
based on R8A774C0 SoC.
DTS files apart from r8a774c0-ek874-u-boot.dts and r8a774c0-u-boot.dtsi
have been imported from Linux kernel 5.11 commit f40ddce88593
("Linux 5.11").
