prom_putchar() is used centrally in early printk infrastructure therefore
at least MIPS should agree on the function return type.
[paul.burton@mips.com:
- Include linux/types.h in asm/setup.h to gain the bool typedef before
we start include asm/setup.h elsewhere.
- Include asm/setup.h in all files that use or define prom_putchar().
- Also standardise on signed rather than unsigned char argument.]
