[PATCH] arm/start.S: Do not use a scratch register to hold the stack pointer

[Sebastian Huber]

Hello Chris,

I am not sure, if using r8 is the right thing to do since r8..r14 are 
banked in FIQ mode. I think the bsp_start_arm_drop_hyp_mode needs to be 
changed to not touch r3, it can use r1 instead.
