Is CONFIG_REGULATOR_VEXPRESS actually required to get QEMU working properly? We definitely don't need CONFIG_REGULATOR_FIXED_VOLTAGE because config ARCH_VEXPRESS has "select REGULATOR_FIXED_VOLTAGE if REGULATOR".

Enable the Versatile Express voltage regulators by default. This should work on all verstatile express platforms and not enabling it prevents a defconfig'ed kernel from using the SD card controller on the qemu emulated platform, which is unfortunate for first-time casual users.
