[RESEND PATCH] MIPS: ftrace: Declare ftrace_get_parent_ra_addr() as static

[WangYuli]

Declare ftrace_get_parent_ra_addr() as static to suppress clang
compiler warning that 'no previous prototype'. This function is
not intended to be called from other parts.

Fix follow error with clang-19:

arch/mips/kernel/ftrace.c:251:15: error: no previous prototype for function 
'ftrace_get_parent_ra_addr' [-Werror,-Wmissing-prototypes]
  251 | unsigned long ftrace_get_parent_ra_addr(unsigned long self_ra, unsigned 
long
      |               ^
arch/mips/kernel/ftrace.c:251:1: note: declare 'static' if the function is not 
intended to be used outside of this translation unit
  251 | unsigned long ftrace_get_parent_ra_addr(unsigned long self_ra, unsigned 
long
      | ^
      | static
