ARM: vexpress: refine dependencies for new code
The versatile express changes for 3.16 introduced a number of build regressions for randconfig kernels by not tracking dependencies between the components right. This patch tries to rectify that: * the mach-vexpress code cannot link without the syscfg driver, which in turn needs MFD_VEXPRESS_SYSREG * various drivers call devm_regmap_init_vexpress_config(), which has to be exported so it can be used by loadable modules * the configuration bus uses OF DT helper functions that are not available to platforms disable CONFIG_OF * The sysreg driver exports GPIOs through gpiolib, which can be disabled on some platforms. * The clocksource code cannot be built on platforms that don't use modern timekeeping but rely on gettimeoffset.
