[U-Boot] [PATCH 1/1] ARMv8: fix error in freeing stack frame

From: zijun_hu zijun_hu@htc.com
relocate_code() allocates 32 bytes stack frame but only 16 bytes are freed before return. it will cause errors to possible previous frames and doesn't make relocate_code() look like a function.
fix by freeing 32 bytes stack space
