Subject: [PATCH v1 2/2] arm64: dts: exynos990: Add the peric0/1 sysreg node

Add sysreg nodes for the PERIC0 and PERIC1 domains.
These system registers are used for peripheral configuration
and control in Exynos990.

Each sysreg node includes its base address, register size, and clock
dependencies.
