parisc/ftrace: add missing CONFIG_DYNAMIC_FTRACE check



[ Upstream commit 250f5402e636a5cec9e0e95df252c3d54307210f ]

Fixes a bug revealed by -Wmissing-prototypes when
CONFIG_FUNCTION_GRAPH_TRACER is enabled but not CONFIG_DYNAMIC_FTRACE:

 arch/parisc/kernel/ftrace.c:82:5: error: no previous prototype for 'ftrace_enable_ftrace_graph_caller' [-Werror=missing-prototypes]
    82 | int ftrace_enable_ftrace_graph_caller(void)
       |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
