Re: [PATCH v2 3/8] ARM i.MX6q: Add GPU, VPU, IPU, and OpenVG resets to System Reset Controller (SRC)

The SRC has auto-deasserting reset bits that control reset lines to
the GPU, VPU, IPU, and OpenVG IP modules. This patch adds a reset
controller that can be controlled by those devices using the
reset controller API.

We now architecturally depend on RESET_CONTROLLER, so need to have
Kconfig to reflect that.  Not sure if it's the best solution, the
following is what I have.

drivers/reset/Kconfig:

config ARCH_HAS_RESET_CONTROLLER
	bool

menuconfig RESET_CONTROLLER
	bool "Reset Controller Support"
	default y if ARCH_HAS_RESET_CONTROLLER

arch/arm/mach-imx/Kconfig:

 config ARCH_MXC
        bool "Freescale i.MX family" if ARCH_MULTI_V4_V5 || ARCH_MULTI_V6_V7
+       select ARCH_HAS_RESET_CONTROLLER
        select ARCH_REQUIRE_GPIOLIB
        select ARM_PATCH_PHYS_VIRT
        select AUTO_ZRELADDR if !ZBOOT_ROM
