Subject: [PATCH] powerpc: Make some symbols static

The sparse tool complains as follows:

arch/powerpc/kernel/btext.c:48:5: warning:
 symbol 'boot_text_mapped' was not declared. Should it be static?
arch/powerpc/kernel/btext.c:49:5: warning:
 symbol 'force_printk_to_btext' was not declared. Should it be static?

These symbols are not used outside of btext.c, so this
commit marks them static.
