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.
