Subject: [PATCH] m68k: Convert missed RODATA to RO_DATA

I missed two instances of the old RODATA macro (seems I was searching
for vmlinux.lds* not vmlinux*lds*). Fix both instances and double-check
the entire tree for other "RODATA" instances in linker scripts.

Reported-by: Geert Uytterhoeven <geert@...ux-m68k.org>
Fixes: c82318254d15 ("vmlinux.lds.h: Replace RODATA with RO_DATA")
