Merge tag 'vexpress-modules-for-soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux into arm/soc

VExpress modularization

This series enables building various Versatile Express platform drivers
as modules. The primary target is the Fast Model FVP which is supported
in Android. As Android is moving towards their GKI, or generic kernel,
the hardware support has to be in modules. Currently ARCH_VEXPRESS
enables several built-in only drivers. Some of these are needed, but
some are only needed for older 32-bit VExpress platforms and can just
be disabled.
