ARM: sunxi: fix build for THUMB2_KERNEL
Building an SMP kernel for the sunxi platform with THUMB2 instructions
fails with this error at the moment:
headsmp.S:7: Error: Thumb encoding does not support an immediate here -- `msr cpsr_fsxc,#0xd3'
Since the generic secondary_startup function already does
the same thing in a safe way, we can just drop the private
sunxi implementation and jump straight to secondary_startup.
