arm64: frace: use asm EXPORT_SYMBOL()
For a while now it's been possible to use EXPORT_SYMBOL() in assembly files, which allows us to place exports immediately after assembly functions, as we do for C functions. As a step towards removing arm64ksyms.c, let's move the ftrace exports to the assembly files the functions are defined in. There should be no functional change as a result of this patch.
