	Add API to save boot parameters passed from BL31 Use assembly implementation of save_boot_params instead of c function. Because generally ATF does not set up SP_EL2 on exiting. Thus, usage of a C function immediately after exiting with no stack setup done by ATF explicitly, may cause SP_EL2 to be not sane, which in turn causes a crash if this boot was not lucky to get an SP_EL2 in valid range. Replace C implementation with assembly one which does not use stack this early, and let u-boot to set up its stack later.
