[PATCH v2 1/3] powerpc: ps3: move udbg_shutdown_ps3gelic prototype

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Allmodconfig kernels produce a missing-prototypes warning:

arch/powerpc/platforms/ps3/gelic_udbg.c:239:6: error: no previous prototype for 'udbg_shutdown_ps3gelic' [-Werror=missing-prototypes]

Move the declaration from a local header to asm/ps3.h where it can be
seen from both the caller and the definition. As suggested
by Michael Ellerman, remove the CONFIG_PS3GELIC_UDBG option to
prevent this from causing a build regression.
