arm64: dts: renesas: r8a77990: Add secondary CA53 CPU core

Browse Source 
Add a device node for the second Cortex-A53 CPU core on the Renesas
R-Car E3 (r8a77990) SoC, and adjust the interrupt delivery masks for ARM
Generic Interrupt Controller and Architectured Timer.

Based on a patch in the BSP by Takeshi Kihara.
