This adds initial and compulsory device tree support to the Gemini ARMv4 platform. We are selecting a bunch of "absolute minimals" for getting a working system up with just device tree: - We select USE_OF for natural reasons or nothing works. - We select CLKSRC_OF and GEMINI_TIMER so we get timekeeping from the clocksource. - We select GPIO_GEMINI because these are used as irqchips, and for a generic driver it is not reasonable for those to have to select every possible irqchip in the world to work, the platform should simply provide the available irqchips. - We select a UART that can be exprected to work with SERIAL_OF_PLATFORM which is the name for an 8250 OF-probed serial port. - We select the syscon-based reset controller: it's not fun when "reboot" doesn't work because of Kconfig, so we just select POWER_RESET and POWER_RESET_SYSCON. - We perhaps a bit controversiallt select ARM_APPENDED_DTB, because this platform is using the ancient RedBoot, and can *NOT* be expected to upgrade its bootloaders. Appended device tree is simply how these devices have to work with device tree.
