Since the BSP bit is writable on real hardware, during reset all the CPUs which were not chosen to be the BSP should have their BSP bit cleared. This fix is required for KVM to work correctly when it changes the BSP bit. An additional fix is required for QEMU tcg to allow software to change the BSP bit. Backports commit 9cb11fd7539b5b787d8fb3834004804a58dd16ae from qemu
