Subject: [PATCH v2 3/5] arm64: dts: add dts files for bcmbca soc 63158
Add dts for ARMv8 based broadband SoC BCM63158. bcm63158.dtsi is the
SoC description dts header and bcm963158.dts is a simple dts file for
Broadcom BCM963158 Reference board that only enable the UART port.
Signed-off-by: William Zhang <william.zhang@...adcom.com>

Changes in v2:
- Change internal bus address and size cells from 2 to 1
- Fix pmu compatible string
- Remove unnecessary cpu_on and cpu_off properties from psci node
- Add the missing gic registers and interrupts property to gic node
