ARM: zynq: reserve space for jump target in secondary trampoline
Add a zero argument to the .word directive in zynq_secondary_trampoline. Without an expression the assembler emits nothing for the .word directive. This makes it so that the intended range is communicated to ioremap and outer_flush_range in zynq_cpun_start; e.g. for LE trampoline_code_size evaluates to 12 now instead of 8. Found by inspection. I'm not aware of any real problem this fixes. Tested by doing on online/offline loop on ZC702.
