mips: unify prom_putchar() declarations

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.]

MIPS: lantiq: fix early printk

The code was using a 32bit write operations in the early_printk code. This
resulted in 3 zero bytes also being written to the serial port. This patch
changes the memory access to 8bit.

MIPS: Lantiq: Add initial support for Lantiq SoCs

Add initial support for Mips based SoCs made by Lantiq. This series will add
support for the XWAY family.

The series allows booting a minimal system using a initramfs or NOR. Missing
drivers and support for Amazon and GPON family will be provided in a later
series.

[Ralf: Remove some cargo cult programming and fixed formatting.]
