In commit 7a22d6321c3d ("powerpc/mm/radix: Update command line parsing for
disable_radix") an `if` statement was added for a possible empty body
(prom_debug).
Fix the following warning, treated as error with W=1:
arch/powerpc/kernel/prom_init.c:656:46: error: suggest braces around empty
body in an ‘if’ statement [-Werror=empty-body]
