qemuarm: Swap for an arm7ve (A15) configuration

Add new QEMU BSP for a Arm Cortex-A15 system and use this as qemuarm,
moving the old armv5te Versatile PB based machine to qemuarmv5.

The new machine uses the QEMU virt machine type, which should be
faster to emulate and updates the qemuarm support to a modern
architecture.
