Subject: [PATCH] ARM: ftrace: MODULE_PLT: Fix build problem without DYNAMIC_FTRACE

From: Alexander Sverdlin <alexander.sverdlin@...ia.com>

FTRACE_ADDR is only defined when CONFIG_DYNAMIC_FTRACE is defined, the
latter is even stronger requirement than CONFIG_FUNCTION_TRACER (which is
enough for MCOUNT_ADDR).

Fixes: 1f12fb25c5c5d22f ("ARM: 9079/1: ftrace: Add MODULE_PLTS support")
