[PATCH v1 1/2] arm64: asmlinkage: Enable use of BTI_C macro in SYM_CODE

[Mark Brown]

SYM_CODE sections may require BTI landing pads but won't have them
automatically generated by the symbol definiton macros. Make an empty
version of the BTI_C macro available so that they can more easily create
the landing pads if they need them.
