powerpc: Fix build error due to is_valid_bugaddr()
[ Upstream commit f8d3555355653848082c351fa90775214fb8a4fa ]
With CONFIG_GENERIC_BUG=n the build fails with:
arch/powerpc/kernel/traps.c:1442:5: error: no previous prototype for ‘is_valid_bugaddr’ [-Werror=missing-prototypes]
1442 | int is_valid_bugaddr(unsigned long addr)
| ^~~~~~~~~~~~~~~~
The prototype is only defined, and the function is only needed, when
CONFIG_GENERIC_BUG=y, so move the implementation under that.
