[PATCH 0/3] arm64: dts: berlin4ct: add GPIO support

[Jisheng Zhang]

Marvell berlin4ct SoC has 6 GPIO ports powered by snps,dw-apb-gpio. patch1
enables ARCH_REQUIRE_GPIOLIB for ARCH_BERLIN. patch2 add GPIO nodes in the
SoC dtsi. The last patch add board dts file for STB reference board.

[PATCH 1/3] arm64: berlin: enable ARCH_REQUIRE_GPIOLIB

[Jisheng Zhang]

All berlin SoCs have GPIOs driven by the dwapb GPIO driver. Add GPIOLIB
as a dependency to be able to support them.

This is missing the corresponding Makefile change to add the
board to the default dtb build list.

I've fixed it up and

Applied the two dts patches to berlin64/dt
