Re: [PATCH v3 2/2] arm64: Unconditionally override SYM_FUNC macros

Currently we only override the SYM_FUNC macros when we need to insert
BTI C into them.  Since we now unconditionally provide the BTI_C macro
used to do that let's always override them, that way any issues with our
overrides it'll show up more consistently.

Since this means that we now have an unconditional definition of BTI_C
update the other users to remove the ifdefs around usage, making them
look a bit neater.
