[PATCH] powerpc: Make early debugging configurable via Kconfig
This patch adds Kconfig entries to control the early debugging options,
currently in setup_64.c.
Doing this via Kconfig rather than #defines means you can have one source tree,
which is buildable for multiple platforms - and you can enable the correct
early debug option for each platform via .config.
I made udbg_early_init() a static inline because otherwise GCC is to daft to
optimise it away when debugging is off.
Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.
