treewide: remove current_text_addr
Prefer _THIS_IP_ defined in linux/kernel.h.
Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.
This patch removes the final call site of current_text_addr, making all
of the definitions dead code.
[akpm@linux-foundation.org: fix arch/csky/include/asm/processor.h]
